Mouse Double-Click Test
Detect a chattering mouse switch by timing the gap between your clicks.
Updated July 10, 2026
How to use the mouse double-click test
- 1Click the test area with single clicks, as you normally would.
- 2Watch the interval between clicks.
- 3Look for intervals under 70 ms flagged as chatter.
- 4Reset and repeat to confirm a consistent fault.
Common uses
- Diagnosing a mouse that double-clicks on single clicks
- Confirming a switch fault before a warranty claim
- Checking a used mouse before buying
- Verifying a repair or debounce setting worked
Frequently asked questions
What causes a mouse to double-click on its own?
A worn mechanical switch. Over time the metal contact inside bounces, so one press makes electrical contact twice, and the computer sees two clicks milliseconds apart. It's the most common way a mouse fails, and it gets worse with use.
How does this test detect it?
It times the gap between your clicks. When you single-click, real intervals are hundreds of milliseconds apart. If the tool records clicks under about 70 ms apart while you're clicking once, that's chatter — the switch firing twice for one press. Deliberate double-clicks will read short too, so the tell is short intervals when you meant one click.
Can I fix a double-clicking mouse?
Sometimes. Options include lowering the debounce time in the mouse software if available, cleaning or replacing the switch (a common repair for enthusiasts), or claiming a warranty. If it's out of warranty and you can't solder, replacement is usually the practical fix.
About this tool
The mouse double-click test diagnoses the double-click fault, where a worn switch bounces and registers one physical press as two clicks a few milliseconds apart. Click the target normally and it times the interval between clicks, flags any under 70 milliseconds as suspected chatter, and tracks your fastest interval and click count. If you single-click but see sub-70-millisecond intervals, the switch is likely failing — the everyday symptom of files opening on one click or drags dropping. All measurement is local in your browser; nothing is recorded.
