Rapid Trigger Keyboard: What It Does and Who Needs It

A rapid trigger doesn’t improve the responsiveness of a keyboard or speed up the process by which the computer receives the keystroke, however it does affect how fast a keyboard “stops” sending signals for a key that you have not physically released yet. The traditional mechanical keyboards use a solid clicking mechanism that keeps the key “on” until the key returns to a certain point after the user releases it. Rapid trigger keyboards, on the other hand, activate as soon as you start to lift your finger, which allows them to provide a vastly more responsive feel than a traditionally mechanical keyboard. The major misconception regarding rapid trigger keyboards is that they provide an increased rate of response to the computer in terms of keystrokes, when in fact, they only do so in relation to the time in which the computer will stop receiving input.

There is a wide range of keyboards that provide rapid trigger features, from entry-level to premium-priced units, and the manufacturing price of these keyboards (the financial production costs) does not necessarily indicate the quality of the rapid trigger implementation or if it has been enabled or disabled as it was received from the factory. Many of these units come out of the factory with the rapid trigger feature disabled, so the keyboard you purchase on the shelf will not have the same rapid trigger tech and feel as the one that was reviewed. In summary, the rapid trigger keyboard changes the way in which the keyboard sends inputs and when the game(s) you play recognize those inputs.

What rapid trigger actually changes on a keypress

When you press a key on a traditional mechanical switch, two things happen at two fixed points. There is an actuation point (or point of contact closure) where the key gets actuated, and an input register (or point of contact with the PCB) where the input is recorded. Once a key has been actuated, it will stay actuated until it goes back up past the reset point, which is higher than the actuation point.

The distance between these points is known as hysteresis, and this is what allows you to lift your finger up far enough before being able to fire the same key again. The Cherry MX Red is an excellent example of this: as per the rapid trigger tutorial from ProSettings, the key will actuate at 2.0mm, while the entire key travels 4.0mm before the switch resets and will not actuate again until it has returned back above the actuation point.

Contact switches do not do a better job of this than contact switches; all they provide is two states: either pressed or not pressed. Corsair describes the mechanical function of contact switches in blunt terms. When two contacts meet and make contact with each other, they “bounce microscopically before settling.” Therefore, it must apply a small debounce delay in order to prevent registering one press as multiple presses; therefore, Corsair states that there is no way to change the actuation point after it has been manufactured.

Magnetic switches and Hall effect switches use different operating principles. The keyboard uses a magnet located in the key shaft, with a Hall effect sensor under the board. Therefore, the keyboard can track the position of the key throughout its entire travel path by reading a continuous position value. This continuous read capability allows all features in this class to exist as there is no firmware update for a keyboard unable to sense its own keys being depressed or moved.

With rapid trigger, the reset point is deleted. Instead of waiting until the key has cleared a predetermined distance to deactivate, when the key reverses direction at a particular distance, the keyboard deactivates the input immediately. As Wooting’s description states, the keyboard will “instantly deactivate the key when you mean to deactivate it.” Additionally, the keyboard can reset within one-tenth of a millimeter of actuation, allowing for very tight resetting of keys.

The actuation point, however, does not change. This is the biggest misunderstanding of this entire subset of the switch category — rapid trigger only enacts changes when the key is turned off, not when it is turned on. The depth that you must type to trigger a keypress is dependent upon the adjustable actuation. The description of Wooting’s setup guide classifies rapid trigger features as removing the “fixed reset point” of a switch, while saying nothing about the depth the initial press is set to. Corsair has actuation functionality set as one toggle, while rapid trigger is defined throughout the entire toggle grouping, and allows for adjustments in both scenarios and maintains the same reset points of their respective toggles.

In the same menu two additional controls are located which often cause the same confusion between users. “Adjustable Actuation” determines how far your keyboard presses have to travel before sending an input signal. “Continuous Rapid Trigger (CRT)” keeps the key registering below its actuation point and is useful only with deeper actuation settings; Wooting notes that CRT matters above 2.0 millimeters and has “nearly no effect” between 0.1 and 0.5 millimeters since the key will be registered in real time.

So what does this mean for you when purchasing a new keyboard? CRT will be automatically disabled on most boards. For example, according to the Corsair K70 PRO TKL manual, “CRT” is turned off at the factory default setting with an actuation setting of 2.0 mm. According to Razor’s product documentation, “CRT” will not work with the factory default profile; you must load a different profile first before using it. Wooting was introduced in 2019 so by now the application of this technology is well understood, but factory default states of keyboards are not yet standardized.

Who actually gets something out of rapid trigger

The only occasion rapid trigger will come into play is when your game cares when an input ends (i.e., when it receives the information). Tactical shooters are a good example of this. In both Valorant and CS2, for example, how accurately you can fire your weapon is dependent on your movement state. The split second between when I begin to lift my strafe key and when my game recognises that release is the difference between firing a shot while standing still and firing while I’m moving. Counter-strafing; stop-and-shoot timing; jiggling or shoulder peeks; the small directional changes that make up a duel are all dictated by the timing of your key releases.

This explains why the way the community describes the benefit of rapid trigger has to do with “feel” rather than a time taken to execute. There has been one particular r/GlobalOffensive thread that has a player referencing a “jump from 144hz to 240hz monitor” when discussing rapid trigger, as opposed to the jump from 60hz – it’s a noticeable difference but nothing too drastic. Another player stated it much better: “Rapid trigger is insane for the underwhelming CS2 movement… counter-strafing is more precise,” and advised those who have already purchased a decent board to “just hold onto it.”

Rhythm games represent the second instance and are probably the most pure representation. osu! and similar games reward you for consistently tapping the same key multiple times. This means that a fixed reset point will punish you most for this motion. Fighting game reversal timing and parrying are similar in that you are required to tap a key to register and release within a window, which a fixed reset can take away from you.

When it comes to keyboards, the boundary is where most people make their biggest mistakes. Most people will never play an aim trainer, and that’s OK, but aim trainers aren’t the real answer. Any game with a movement system that punishes players for quickly switching directions — such as games that rely on rapid acceleration and momentum — will see a benefit in how quickly you can release your key presses. A faster key release will create a more “twitchy” character, not a more responsive character.

There is no way to provide an answer to the typing question, because there is no answer. The only thing we have available is what the manufacturer tells us, and they tell us one thing: Corsair’s Keyboard Quick Setup Guide suggests turning rapid trigger off for typing, and setting the actuation point to 3.0mm (2.0mm with actuation) for everything that you type. Corsair’s Quick Setup Guide states that “if you press deeper than you need to in order to type, you are more likely to make a mistake and accidentally press the wrong key.”

The movement vs aim line is worth keeping, because that is where the marketing often overshoots the mark. Rapid trigger works in the same way that a quick release works. Rapid trigger does not change where your crosshair is, nor does it improve the way that you track your target, nor does it improve the way you play. The only people who benefit from rapid trigger are those who are already fast enough that they are experiencing a delay due to hardware.

If you’re complaining about a lack of accuracy with your aim, then upgrading your other hand’s input device will have a more immediate impact on that issue. For the specific complaint about lack of accuracy, a higher-quality mouse would have a larger impact than a premium keyboard would.

What the latency numbers prove, and what they don’t

All marketing numbers in this segment mean different things to buyers and have arithmetic discrepancies. As an example, RTINGS has published an analysis that summarizes keyboard testing on an established testing setup (bench) with its research into the rapid trigger latency – they state that your response time (and how consistently you are able to repeat it) “will outweigh pre-travel latency by at least an order of magnitude.”

This changes the way we view this functionality. Rapid trigger provides an incremental benefit in the context of where the human being represents the majority of what happens, thus giving you good reason to purchase without hesitation IF YOU ARE THE RIGHT PLAYER; otherwise, rapid trigger has no point of purchase, as someone not suited for this advantage will not utilize the benefit.

The second limitation of the numbers is that they do not indicate which keyboard is the fastest, given that the since the majority of published comparisons do not have the necessary match-up. Therefore, there is a process you need to utilize before accepting any keyboard latency number from a review.

1. Check what presses the key. The credible rigs use a machine to emulate a finger, because a machine holds press depth and speed constant while yours varies.
2. Check when the clock starts and stops. RTINGS’ latency test method starts timing the moment the solenoid makes contact with the key, and stops when the keyboard sends the input — intercepting that USB transaction with a Beagle 480 USB Analyzer.
3. Check the sample count. RTINGS collects 200 samples per test and plots them, which surfaces outliers and consistency problems a single average hides. A board that averages well but spikes badly is worse than its average suggests.
4. Check the settings protocol. RTINGS tests at the most sensitive configuration — lowest debounce, maximum polling, most sensitive actuation and rapid trigger. That’s the best case, not the default you’ll unbox.

The last point is the part that most readers overlook. A published figure showing maximum polling and minimum actuation (keys pressed) gives you an insight into how the keyboard can be built.

But here’s the big catch—what you think is an accurate measurement for latency based on polling frequency is really not. An 8,000Hz key switch may send messages to the PC at a fixed, extremely short polling frequency, but that frequency does not correlate with how long it takes for your finger to press down the key before it sends the message. The figures that appear on countless forums are all in that same range and are completely unusable until after a true, accurate test has been conducted on them. If you find a site that publishes per-board time measurements, but does not have a stated method for measuring it, then there is no way to directly compare it with another site’s time measurement that has a stated method.

This article does not include per-board time measurements in any of them; therefore, when you see those numbers published in this article, they should only be used to evaluate the keyboards compared to each other, as the independent laboratory that performed all of the tests will inform you that no more than two years ago, most, if not all of the differences had little or no meaning anymore.

In July 2025, RTINGS published a report on their testing of rapid trigger release behaviour on three different types of gaming keyboards using a servomotor-driven cam to create a controlled environment. During testing, all gaming keyboards that could utilize rapid trigger release technology displayed release latency from 1 millisecond to 18 milliseconds. The results indicate that the “spread” of release latencies is smaller than the difference between the fastest Olympics sprinters. The study concluded that the difference in latency between the various models tested was so small that it was unlikely to have a significant effect on performance in a highly competitive environment. Therefore, the company has now stopped providing any release latency data on its website.

On the other hand, TechGearLab’s keyboard testing was able to “disconfirm” some of RTINGS’ findings. The company conducted its own tests on 17 separate keyboards using their own latency testing rig, and discovered that “Hall Effect Switches do not necessarily provide superior response times.” Their SteelSeries Apex Pro Gen 3 Hall effect keyboard had a higher latency than the standard mechanical Logitech G915 X Lightspeed.

Combining the two reports offers a broader perspective than the marketing claims suggest. While Hall Effect Keyboard technology provides players with the ability to customize their keyboard’s response time to a greater degree than traditional keyboards do, it does not guarantee that they will provide the fastest response times or even faster than other modern keyboards.

The actuation depth is where a true advantage originates from; therefore, that is a setting rather than an attribute of the product. As per the report from RTINGS on the research again, at extremely shallow actuation levels, you will tap keys with any amount of vibration on the table surface. The brief pre–travel setting only helps individuals with exceptional ability to take advantage of the optimum settings; it does not increase the execution speed from one keyboard versus the other. You will be able to set up your keyboard to increase your ability to type faster based on a configuration set by you.

How Wooting, Razer, and Corsair implement it differently

The way these three implementations operate at different speeds are not as much a determining factor; but rather, the locations of their settings, the type of action performed by this board when you first plug it in, and how much control over the board you can exert without downloading additional vendor-branded applications — all of which are important considerations for players using a locked-down tournament machine.

In general, the practical values of three specific items in the table are what we would consider the most important.

The first would be Corsair’s recommended range for adjustable actuation. They say you can set an actuation ‘on the fly’ anywhere from 0.1mm to 4.0mm, but in small print they recommend using the range of 0.3mm – 3.6mm for optimal accuracy. According to them, adjusting your actuation out of this recommended range will provide greater sensitivity, but may also negatively impact the consistency of your keyboard action. The first number is a representation of what the hardware can be set to, and the second number represents how the manufacturer thinks people should use them. These two numbers do not match up, so only one number was printed on the packaging.

The second component would be what is referred to as partial coverage. The K70 PRO TKL features 61 keys with magnetic switches; however, 23 of these are standard linear mechanical switches with a fixed actuation point of 2.0mm and no ability to use a rapid trigger. The reason for this difference in functionality is you cannot program the key that does not contain a magnet to be adjusted, which means that one of the features being advertised will not work for all keys on the keyboard.

Naming is the third element. There are four different brands; Snappy Tappy, Snap Tap, FlashTap, and Rapid Tap. They all represent the same thing – Simultaneous Opposing Cardinal Directions (SOCD). When you press left and right on a normal keyboard, both presses cancel each other out. SOCD picks one side and uses it instead of cancelling out both sides. Corsair has a Hall effect (a magnetic switch) within its explanation of SOCD that is separate and distinct from the rapid trigger. This selection carries a unique risk profile from the other types of SOCD because each type is treated as a separate function from a hardware trigger perspective.

Onboard shortcuts are the reason why keyboards that have the rapid trigger capability can be configured at a LAN. Razer’s product requires no software to enable the actuation point or make adjustments to the rapid trigger. Wooting’s profiles will stay on the keyboard for use on any computer, even those running non-Wooting OSs. Finally, Corsair has the onboard actuation point and sensitivity settings in the firmware, including the ability to calibrate the onboard actuation point using just the keyboard, which is useful for when the actuation point has moved from where it was set by default. The hardware calibration routine is reachable from the keyboard itself.

Corsair goes even a step further than the other manufacturers by adding a one-button GAME MODE that will enable rapid trigger, lock Windows keys, and set a static colour. However, there is a drawback to switching polling rates while in GAME MODE. It can take as much as a second to change the polling rate when in GAME MODE, so don’t switch polling rates until you are in the match, or waiting for the match to start.

Price points vary widely enough in this category that it isn’t possible to provide only one answer on price — budget-price magnetic boards are priced significantly below flagship products, while the prices for retailer listings are constantly changing. Wooting’s 60HE v2 was listed as $179.99 direct from Wooting as of September 18, 2026, from a U.S.-based retailer. For all other magnetic boards, consumers should visit the retailers’ websites for the most up-to-date pricing and availability; the pricing referenced in reviews will typically become out-of-date quickly.

When looking for keyboards with rapid trigger capabilities, the most commonly searched brand is Wooting, and “wooting rapid trigger” is often used as a shorthand reference for the standard to which all other brands will be judged against. As of now, the fact that Wooting uses a rapid trigger capability is no longer unique to Wooting; many similar products are being offered by competing manufacturers. With three different types of control surfaces and three types of onboard adjustment mechanisms, the true differentiator for buyers of these products will most likely not be which one has the fastest response but which one is able to be configured properly on the specific machine on which they play.

What you give up when you buy the feature

There are four separate costs here, and buyers tend to notice only the first.

• No tactile option exists anywhere in the category, at any price. Magnetic switches need a magnet in the stem that a sensor reads through the full travel path, and every one of them is linear. If you type all day on a board with a tactile bump, no rapid trigger keyboard replaces that feel — not the budget ones, not the flagships. This is the biggest reason mixed-use buyers bounce off the category.
• The cheap end fails on firmware and software, not switches. The magnet and sensor that make a Hall effect key work are inexpensive, which is why budget magnetic boards exist at all. What separates a budget board from a flagship is the stability of the firmware, the quality of the configuration app, and whether the vendor maintains both. A board you can’t configure reliably is a board with a fixed actuation point at a premium price.
• You’re buying into a vendor app. The features you paid for are reachable through the manufacturer’s app or the board’s own onboard tables, and if you play on a competition PC where you can’t install software, only the onboard controls work.
• Actuation and reset points are firmware state, not hardware state. Firmware updates can overwrite stored profiles, and per-key rapid trigger sensitivity isn’t available on every hardware revision. Check the exact SKU’s changelog before assuming a feature shown in a review exists on the board in your cart.

Misdiagnosis is the second-most-common complaint when it comes to buyers experiencing false triggers (this is when a key fires when you weren’t actively pressing it). A board that has ultra-shallow actuation will cause a key to register almost immediately (e.g., as soon as you start thinking about pressing it). If you rest a finger on a keycap or bump your desk, this will usually result in the key firing. The recommendations made by the community on how to set up your keyboard most often suggest you raise the actuation to around 0.3-0.4mm because you won’t feel the difference in latency between these distances and can definitely feel the misfire.

In most cases, this is a configuration issue, not a defect. SteelSeries released a feature called Protection Mode with the APEX Pro Gen3 which (according to TechGearLab’s testing) “dynamically adjusts the actuation point of adjacent keys to help reduce accidental presses while typing” — this indicates that the manufacturer recognizes that ultra-shallow actuation presents an inherent hazard of design rather than of user error. That said, there may be instances where an owner experiences ghosting caused by their configuration, and the resolutions to these problems are opposite.

Hardware-based problems, on the other hand, have an entirely different signature; in these cases, an individual key is registering and triggering a response without the user activating it, even if it has been recalibrated and/or updated, and only after replacing the circuit board does the issue resolve itself. Treat a single misfiring key as a question of hardware, not tuning; and recognize that while these reports are made by individuals through community threads, these types of posts validate the failure mode exists but do not provide an understanding of how many users experience this issue.

On the software side, another practical trap is that Corsair’s iCUE runs the board in “software mode” while the application is open. Therefore, the values established within the application may differ from those produced by the onboard hardware tables when the application is not currently running. Therefore, if you are setting up your equipment prior to a tournament, you should complete the setup in “hardware mode”.

The final cost is more of a limitation on the range of products available, rather than a defect in a specific keyboard. Everything above deals primarily with the keyboard; however, the rapid trigger does not take into account the other end of the timing chain, which includes the display, frame rate of the mouse, and mouse polling. The time between frames for a 144 Hz panel is much greater than any latency difference for the keyboards mentioned. Therefore, spending money to fix the keyboard term within a system in which the largest term is associated with the display is a waste of money. If your system is restricted by budget considerations, it is worth clarifying that a responsive membrane keyboard will not restrict your overall performance.

Where rapid trigger is allowed and where it gets you kicked

The focus of this concern has shifted to an incorrect feature. In August 2020, Valve limited the use of input automation with respect to SOCD (Simultaneous Opposite Cardinal Directions) capabilities such as the Snap Tap from Razer and Snappy Tappy from Wooting, allowing players to swap strafe directions automatically rather than rely on experience to develop their release timing for this skill set.

Rapid trigger is not covered under this definition of input automation nor has the enforcement of this feature ever been utilized as such.

The essential point is that SOCD penalty on Valve servers is a Kick, not a Ban. According to a hands-on test from The Verge, when a player experiences SOCD, he will be kicked from the game and will not receive a ban on his account. Valve restricts the use of this feature to players “suspected of using automation to perform multiple player inputs from a single game input” and limits this to “initially – exclusively on Valve’s Official Servers”.

Corsair (Creator of FlashTap, which is one of the banned types of SOCD in CS2), states its stance in its own Rules article for CS2: Rapid Trigger Keyboards are not banned, and using Corsair equipment will not cause immediate bans as long as FlashTap is disabled. Additionally, FlashTap is disabled by default on Corsair’s hardware and software.

Fixing this issue practically, as opposed to in theory, is easier than it seems, and is simply a matter of visually checking the status of your Corsair K70 PRO TKL keyboard, or another Corsair keyboard equipped with FlashTap. FlashTap is turned “On” only when there are either two solid red lights on the board (Game Mode), or when the A and D keys are yellow. If neither is present, FlashTap is not activated on the board; therefore, check whether or not you are using FlashTap before you queue into a match.

The confusion does not stop there. FACEIT states that its keyboard rules allow SOCD for all of FACEIT’s supported platforms; they clarify that SOCD is aligned with ESL Pro Tour rules while prohibiting the use of null binds for the ESEA League and EPT Open Qualifiers. Valorant has no restrictions, and Wooting has included a warning in its Valorant Guide about disabling the SOCD feature when playing on Valve servers. For many other popular esports titles, there are no rapid-trigger-specific published policies, and community reports indicate instances of support staff not being able to provide a clear response — meaning that an absence of a policy cannot be interpreted as permission.

Lastly, there is a failure mode to consider that is not a rules question. The software used in anti-cheat searches for patterns of input that look like they have been automated; therefore, having a keyboard set-up to register keystrokes that are spaced several milliseconds apart can resemble that.

Players of The Finals who were kicked out of the game due to their use of rapid trigger reported that their keystrokes were landing at approximately 30 milliseconds apart. However, other players in the same thread reported that they were not having issues with the same keystroke settings. Support could not give a definitive answer as to why these players were kicked. The issue was more due to anti-cheat false positives than rule infractions, and the only way to resolve it is with milder settings — not a different keyboard.

A rapid trigger setup that switches quickly is allowed for use in nearly all scenarios where this use can be verified. SOCD is the configuration option used by the majority of companies to enforce these rules.

When players compete in multiple titles, the practical rule is that they must pay most attention to SOCD and generally not to rapid trigger setups. Players should maintain a set of profiles associated with each title, confirm that they have the correct visible indicators when changing titles, and validate how the one-button gaming preset functions on each keyboard prior to engaging in online play.

The settings worth changing, key by key

Change only one variable at a time, then check if it still operates correctly before moving on to the next variable. The order of the changes is important: First, set actuation and verify that the key registers are working as expected, then change the reset behavior. If you change both actuation and reset behavior together and something doesn’t seem right afterward, you can’t determine which variable caused it.

1. Set actuation depth on your movement keys and stop there. This is the change that does most of the work, and the one with the largest perceptual range. Resist going shallower than the manufacturer’s own recommended floor.
2. Confirm the key registers where you expect. The test is your hand, not the number in the app. Rest your fingers on the keys the way you actually hold them mid-round — that’s how shallow-actuation problems announce themselves.
3. Turn rapid trigger on for movement keys only. Wooting’s Valorant guidance is to enable it on WASD and nowhere else, and to treat left-Ctrl as an optional addition if you tap crouch between strafes.
4. Set rapid trigger sensitivity inside the published band, then tune for jitter. If your character stutters while you hold a direction, the sensitivity is too low — your finger’s micro-movements are being read as release-and-repress inputs. Raise it until the jitter stops.
5. Leave continuous rapid trigger off until your actuation is deep. It matters at 2.0mm or higher and does essentially nothing below 0.5mm.
6. Save to onboard memory, and build a profile per game. The board’s stored profiles are what travel to a tournament PC.

Here’s the starting profile, drawn from Wooting’s published Valorant ranges and Corsair’s recommended bands. Treat it as a baseline to test, not as a result.

The insight gained from inspecting the table is that the most important keys are shallow. The deepest keys are those that cause issues. For example, movement inputs benefit from having only a short distance to travel when the button is pressed because it allows a user to move the direction with as little finger movement as possible when beginning or stopping that movement. Conversely, any key that can cause an unintended consequence — for example, the Windows key that takes you out of a full-screen game — will be located toward the bottom of the travel range of that key.

The setup guide for Corsair’s rapid trigger feature comes from a different direction but still reaches a similar end point. Instead of turning on rapid trigger for all uses (2mm) and typing (3mm), as listed on the manufacturer’s website for general purpose and typing use, the setup guide suggests turning on rapid trigger for shooters and MOBAs (1mm) only. The guide is authored by the same manufacturer who produces the product page prominently featuring the rapid trigger.

Before configuring any other settings on your keyboard, check for these two items because they impact the ability to customize other settings. When the rapid trigger feature is on, the secondary actuation point for that particular key will be disabled, so it is important to know which actuation point you want to use before configuring that key. Every hardware revision does not support per-key rapid trigger sensitivity, so make sure that the specific product you are testing supports it before assuming it is identical to the product in the review board.

If you have reset your key to the last known working configuration and it continues to misfire, stop adjusting the key in the tuning mode and start following the manufacturer’s troubleshooting process. If only one of your keys does not respond, the issue is hardware based and you will need to reach out to your manufacturer’s support channel for further assistance. When a key survives hardware calibration, it has moved beyond what adjustments made on the settings screen will resolve.

Hall effect, TMR, and optical: which sensor type changes anything

Three different types of sensors are in contention for the same application; the distinctions among the three are minor compared to what marketing claims. Each type of sensor detects the position of a key in a different manner. Hall effect sensors measure the voltage produced by the proximity of a magnet to the sensor and only operate on a single axis. Tunneling magnetoresistance (TMR) detects through multiple axes, allowing for the use of hybrid layouts on keyboards and reducing power draw compared to the Hall effect sensor. The way Razer uses analog optical sensors is to shine a light through the stem of a key and measure the amount of light that passes through, which eliminates the need for magnets.

In terms of practical differences, the hall effect, TMR, and analog optical sensors all have similar characteristics in terms of granularity, power, and cost. Each of the three sensors is capable of providing continuous position readings required by rapid trigger applications, so each of the three sensors will be able to provide the same normal set of features. Since the TMR sensor is able to sense across more than one axis, this allows for new and improved hybrid layouts and reduced power consumption, which is very important for wireless keyboard applications. The Hall affect sensor is the long-established, lowest-cost option, and has the largest number of users/supporting companies. The optical sensor does not experience interference from magnets, but they are proprietary to the companies that develop them.

Consumers should be skeptical about the comparison charts that show TMR as being categorically superior, as those chart comparisons are produced by the retailers and manufacturers of TMR keyboards. There are no independent keyboard level tests that have been done to verify that TMR keyboards perform better than other types of keyboards for the average player, and the one independent laboratory that tested keyboards in this category found that the type of sensor a keyboard uses does not guarantee that it will have a lower response time than a different type of keyboard.

When you remove the positioning difference of these sensors, it becomes a much simpler decision to make on which to use. The Hall Effect sensors are cheaper, easier to acquire across a wide variety of boards, and much more available than TMR (Tunnel Magnetoresistive). While TMR currently has the newer technology, higher costs, added multi-axis sensing, and lower power draw, there is no evidence that TMR’s added capabilities benefit a desktop gamer. Also available as an option is an Analog Optical sensor, which possesses the same capabilities as the aforementioned sensors, but has one less supplier available (as of this writing).

Though each of these sensor types provides a different approach for creating a trackable target for your finger via a mouse pad or desk, they do not change how the user interacts with their mouse. The three types of sensors all offer the same basic feature sets, the same tuning workflows, and the same false trigger behaviour as a result of shallow actuation for all three sensor types — because this trigger behaviour is the result of you and your interaction with your mouse, not the sensor technology that you are using. Therefore, regardless of which sensor you choose to purchase and use, you will configure each of the three sensor types in the same way.

There is, however, at least one fact about each of these sensors that do have a real impact on the buying decision of the buyer: Magnetic and Optical Switches are Linear switch type devices; there is no Tactile bump associated with them. When you switch from a Tactile Mechanical Keyboard to one of these switches, you will immediately see the difference in feeling from the first key press prior to being able to know if latency is an issue or not.

When Rapid Trigger Earns Its Place

You would use the “Rapid Trigger” only when your timing of releases is what is costing you the fight, and so you can configure it based on each key, in both circumstances. Otherwise it does nothing to speed up latency as a result of what an independent lab testing for this category found, where the difference between modern boards was fairly insignificant. The same holds true for purchasing it directly out of the box, as Corsair will release it with a 2.0mm actuation, and Razer will not allow you to see this in the original factory setting (profile). Prior to purchase, if you want to be sure of all three items (the recommended actuation range, whether all keys are magnetic, the default rapid trigger and SOCD states) be sure to look up the manual for the specific SKU number you plan to buy.

Frequently Asked Questions

Does rapid trigger change how far I have to press a key?

No, the trigger does not change until the key comes off the trigger when you let up off of the key. The press depth is controlled using adjustable actuation (which has its own separate control for adjustment). According to Wooting, rapid trigger “removes the fixed reset point of a switch”, and does not include the initial press depth in its description.

Can rapid trigger get me banned?

The Valve restriction put in place in August 2024 does not prohibit a feature. The restriction prohibits input automation (for example, SOCD-specific automatic tools). The kick report for CS2 on The Verge indicated that being caught using an input automation device (such as an automatic SOCD) could result in being kicked from the match but would not result in an account ban. Therefore, make sure to disable your SOCD before connecting to Valve’s servers.

Does rapid trigger make typing faster?

To date, there are no published measurements. According to Corsair’s setup guide, you should turn off rapid trigger while typing and increase actuation to 3.0mm; the reasoning behind this is that a deeper press prevents typographical errors or accidental presses.
