🖱️ Microswitch Debounce Timing
Mouse Double Click Test
Inspect click interval timestamps, measure your fastest double-click speed, and detect faulty microswitch chattering.
DIRECT SUMMARY
What causes unintended mouse double-clicking?
Mechanical microswitches (such as Omron or Kailh switches) rely on metallic leaf springs. Over millions of actuations, contact oxidation and metal fatigue create electrical contact bounce. If bounce occurs faster than the controller debounce threshold (<10–30 ms), a single physical click registers as two accidental clicks.

How to Tell a Fast Click from Switch Failure
Human motor speed limits deliberate double-clicks to approximately 60 ms to 150 ms. If you single-click and the test registers an interval below 30 ms, your microswitch is experiencing hardware contact chatter.
Summary & Verification Takeaways
- Deliberate human double-clicks typically range between 70 ms and 180 ms.
- Intervals under 30 ms indicate physical microswitch contact bounce and spring degradation.
- Optical mouse switches (using light beams instead of metal contacts) are immune to electrical debounce chatter.
