The actuation point is the distance you have to press a key down before the keyboard registers it as pressed. On a traditional mechanical keyboard it is usually fixed at around 1.5 to 2.0 mm, while Hall effect keyboards let you change it in small steps, often from a fraction of a millimeter up to roughly 4 mm depending on the model.
What an actuation point is
Every key has a total travel distance, commonly around 4 mm from rest to bottom-out. Somewhere along that travel there is a point where the switch tells the computer “this key is down.” That point is the actuation point. A shallow actuation point means the key registers early, with only a light press. A deep one means you have to press further.

It is easy to confuse the actuation point with the reset point. The reset point is where the key stops counting as pressed on the way back up. On many standard switches the reset point sits slightly above the actuation point, which creates a small gap called hysteresis. You must lift past the reset point before the key can fire again.
How it works in different switch types
Standard mechanical switches
Classic mechanical switches use metal contacts. Two contacts touch at a fixed point of the stem’s travel and close the circuit. Because it is physical, the actuation point is set by the switch design. Makers publish it in the spec sheet, and you cannot change it with software.
Optical switches
Optical switches use a beam of light that the stem interrupts. They are still mostly fixed in practice, though some designs expose a few preset levels.
Hall effect (magnetic) switches
Hall effect keyboards put a magnet in the switch stem and a sensor on the circuit board that measures how close the magnet is. RTINGS and keyboard makers explain that this gives a continuous reading of key position instead of a simple on/off contact. Because the keyboard knows where the key is at all times, software can pick any point as the actuation point, even a different one for each key. The same sensing also enables Rapid Trigger, which resets the key the instant it starts moving up.
Typical values
| Switch type | Typical actuation point | Adjustable? |
|---|---|---|
| Standard mechanical | About 1.5 to 2.0 mm | No |
| Low-profile mechanical | About 1.0 to 1.5 mm | Usually no |
| Optical | Around 1.0 to 1.5 mm | Limited on some models |
| Hall effect | Set by the user, often from about 0.1 mm to 3.3 mm or more | Yes, by software, often per key |
Exact ranges differ by model. One maker may list a top setting of 3.3 mm while another lists 3.8 mm or 4.0 mm, so read the spec page of the keyboard you are considering.
Why it matters for gaming PCs
Speed of response
A shorter actuation distance means the key fires sooner after your finger starts moving. Reviewers note that the effect on total input latency is small for the press itself, and that Rapid Trigger, which shortens the reset, is often the more noticeable improvement in fast shooters and rhythm games.
Control and accidental presses
The downside of a very shallow setting is accidental inputs. If your fingers rest lightly on the keys, a 0.1 mm or 0.2 mm point can trigger when you did not mean to. Many players choose a slightly deeper point for movement keys and a different one for abilities.
Typing versus gaming
A setting tuned for fast play may be annoying for typing, since shallow settings produce typos. Some keyboards store profiles so you can swap between a gaming set and a typing set.
How to check or set it on your own system
The steps depend on your keyboard model, so use its manual or the maker’s software page for exact menu names. A general process looks like this:
- Confirm your keyboard supports adjustable actuation. Check the spec sheet for words such as “Hall effect”, “magnetic switch” or “adjustable actuation.”
- Install the maker’s configuration software, or open its browser-based configurator if the keyboard supports one.
- Find the actuation or key travel setting. It is often under a section named after the switch feature, a performance tab or a key-tuning tab.
- Pick a starting value. Many guides suggest starting near the middle of the range and moving shallower in small steps.
- Set the reset distance if the software exposes it, and decide whether to enable Rapid Trigger.
- Save the profile to the keyboard’s onboard memory if the option exists, so the setting works without the software running.
- Try the setting in a game or typing test, and adjust 0.1 mm at a time until accidental presses stop.
On a standard mechanical keyboard there is nothing to adjust. The way to change the actuation point is to switch to a different switch model, and on a hot-swap board that means pulling and replacing the switches. Firmware updates carry a small risk, so follow the maker’s instructions and keep the keyboard connected during the update.
Common misconceptions
“Lower is always better”
A very low actuation point increases misfires. Many competitive players report preferring a moderate value over the minimum.
“Actuation point and travel distance are the same thing”
Travel is the full distance the key can move. Actuation is the point within that travel where the input registers.
“Adjustable actuation makes you a better player”
It helps with control and responsiveness, but practice and aim matter much more.
“Hall effect keyboards have no input delay”
They still have the keyboard’s polling rate, firmware scanning and USB timing. The benefit is mainly in the press and reset behavior.
When to care and when to ignore it
| Player type | Should you care? | Notes |
|---|---|---|
| Competitive FPS player | Yes | Fine control of actuation and Rapid Trigger can help with counter-strafing |
| Rhythm game player | Yes | Fast repeated taps benefit from short, tunable resets |
| Casual gamer | Little | Default settings are fine |
| Heavy typist | Some | Prefer a deeper point to avoid typos |
Frequently Asked Questions
What actuation point should I start with?
Many guides suggest a value around 1.5 mm as a neutral starting point, then moving shallower for fast games. Because hands and playstyles differ, adjust in small steps until the keyboard feels comfortable.
Can I change the actuation point on a normal mechanical keyboard?
No. It is a physical property of the switch. You would need different switches to get a different actuation distance.
Does a shorter actuation point reduce latency a lot?
It reduces the time before the key registers, but the difference is measured in a few milliseconds at most. Reviewers generally find the reset behavior and overall responsiveness more noticeable than the press distance alone.
What is Rapid Trigger?
Rapid Trigger is a Hall effect feature that resets the key as soon as you start releasing it and registers a new press as soon as you push down again, instead of waiting for fixed actuation and reset points. Makers describe it as useful for quick direction changes.
Are adjustable keyboards allowed in tournaments?
Rules vary by event. Some organizers have restricted certain keyboard features, so read the rulebook of the specific competition before using one.
Do I need software running for the setting to work?
That depends on the model. Many keyboards store settings on the board, while others rely on the maker’s app. The product manual explains how your keyboard handles it.
