How to use the double click test
- Click inside the box at a normal pace, one deliberate click at a time. Don’t try to click fast.
- Do at least 50 clicks. Faulty switches often double-click only now and then.
- Red entries in the list are presses that came less than the threshold after the previous one: those are the faulty clicks.
- Test the right button too, and the side buttons if you use them in games.
Reading the results
| Result | Meaning |
|---|---|
| 0 faults in 50+ clicks | Your switch is fine. |
| 1–2 faults | Early wear. It will usually get worse; keep an eye on it. |
| Frequent faults | The switch is worn out. Drag-and-drop will fail and games will register extra clicks. |
Fixing a double-clicking mouse
- Warranty: this fault is well known; many manufacturers replace the mouse.
- Debounce setting: some gaming mouse software lets you raise the debounce time, which hides the fault.
- Compressed air: a burst into the gap under the button can clear dust from the switch temporarily.
- Replace the switch: possible on many mice with basic soldering, or hot-swappable on some newer gaming mice.
Check every other button and the wheel with the full mouse test.
FAQ
Why does my mouse double-click when I click once?
The metal contact inside the mouse switch wears out and bounces, so one press closes the circuit twice. It's the most common mouse fault, especially on gaming mice, and it usually gets worse over time.
How does the double click test detect the problem?
It times every press. Nobody can click the same button twice in under about 80 ms on purpose, so two presses closer than that are flagged as one click registered twice. You can adjust the threshold with the slider.
Can I fix a mouse that double-clicks?
Compressed air into the switch sometimes helps for a while, and some mouse software has a debounce setting. The lasting fix is replacing the switch, or the mouse. Check the warranty first: many makers replace mice with this fault.
Could it be a Windows setting instead?
If this test shows no faults but you still get double-clicks in Windows, check Mouse settings → Additional mouse settings → Double-click speed, and make sure File Explorer isn't set to open items with a single click.
