What Is Rapid Trigger? Rapid Trigger vs Snap Tap Explained
Updated
Rapid trigger makes a key reset as soon as it starts moving up and fire again as soon as it starts moving down, instead of waiting to cross a fixed point. Keyboards that can measure how far each key is pressed support it, mostly Hall effect (magnetic) boards. It's popular in competitive shooters because you can stop and change direction faster. It's a different thing from Snap Tap / SOCD, which some games have restricted.
How does rapid trigger work?
On a regular mechanical switch, the key turns on when it passes the actuation point (about 2mm down) and turns off when it comes back up past a slightly higher reset point. You have to lift the key that far before it can fire again.
A Hall effect keyboard knows the key's exact position all the time. With rapid trigger on, it watches the direction:
- Key moving down by a small amount (say 0.1mm) → on.
- Key moving up by a small amount → off, wherever it is in the press.
So a key can turn off and on again without ever coming near the top.
Why is rapid trigger good for gaming?
In shooters like Counter-Strike and Valorant, you're most accurate when you're standing still. With rapid trigger, letting go of a movement key stops you sooner, and tapping it again starts you sooner. Strafing and peeking feel tighter. It also helps in rhythm games and anything with fast repeated taps.
For typing, it doesn't do much, and very sensitive settings can cause accidental presses.
Rapid trigger vs Snap Tap and SOCD
These often get mixed up:
| Rapid trigger | Snap Tap / SOCD | |
|---|---|---|
| What it does | Resets and re-fires a single key based on its movement | Decides what happens when two opposite keys (A and D) are held at once, e.g. the most recent one wins |
| Where it comes from | Analog sensing, mostly Hall effect | Keyboard software; Razer's version is called Snap Tap |
| What it changes | How fast one key responds | Automates switching between two keys |
Is rapid trigger banned?
Rapid trigger itself is generally allowed. The features that have drawn restrictions are the SOCD-style ones that automate switching between opposite keys. In 2024, Valve said Counter-Strike 2 would kick players using that kind of automation on its official servers. Rules vary by game and change over time, so check the current rules of any game you play competitively.
Which keyboards have rapid trigger?
Most Hall effect keyboards, plus some optical and other analog boards. A regular mechanical switch can't do it, because it only knows "pressed" or "not pressed". See are Hall effect keyboards worth it and keyboard switch types explained.
How should you set rapid trigger?
Start with the defaults, then adjust:
- Sensitivity (how far a key must move to change state): smaller is faster but easier to trigger by accident, because tiny changes in finger pressure can release and re-press a key you meant to hold. A common starting range is 0.2–0.5mm; go lower only if your fingers stay steady.
- Actuation point for the first press: a bit deeper avoids accidental movement when you rest your fingers on the keys.
- Which keys: you can usually enable it just on movement keys and leave the rest normal.
Frequently asked questions
What does rapid trigger do?
It turns a key off as soon as it starts moving up and on again as soon as it moves down, so you can re-press without lifting the key all the way.
Is rapid trigger cheating?
Rapid trigger itself is generally allowed. Restrictions have targeted SOCD or Snap Tap-style features that automate switching between opposite keys. Check each game's current rules.
Can mechanical keyboards have rapid trigger?
Not regular ones. A mechanical switch only knows pressed or not pressed. Rapid trigger needs a keyboard that measures key position, like a Hall effect board.
What's the difference between rapid trigger and Snap Tap?
Rapid trigger changes how fast one key resets and re-fires. Snap Tap (SOCD) decides which of two opposite keys wins when both are held.
What's a good rapid trigger sensitivity?
A common starting range is 0.2–0.5mm. Lower is faster but makes accidental presses more likely, so only go lower if your fingers stay steady on held keys.
