Why does my mouse double-click when I click once?
Answer why a mouse creates duplicate clicks, how to confirm switch bounce, and when debounce, repair, or replacement makes sense.
Short answer
The usual cause is switch bounce. A worn or dirty mouse switch can send two electrical transitions from one physical click, which the browser or operating system sees as duplicate clicks.
Confirm first
Click slowly in the double-click test.
Compare left and right buttons.
Repair the switch or replace only after repeat failure.
Why this matters
HWProbe keeps the answer tied to evidence: run the matching browser test, try the reversible fix, then replace only when the same fault repeats. Tests run locally in your browser at hwprobe.com.

Frequently Asked Questions
Can debounce software fix double-clicking? +
Debounce software can hide mild switch bounce for a while, but it does not repair the switch. If duplicate clicks return, hardware repair is the durable fix.
Can wireless lag cause false double-clicks? +
Wireless problems can make clicks feel inconsistent, but repeated duplicate events from slow single clicks are more consistent with switch bounce than lag.
