Mouse Double Click & Switch Chatter Diagnostic Tool
Test your mouse switches for double-clicking faults. Detect metallic leaf chatter under 35ms, identifying failing Omron, Huano, or optical microswitches.
Universal Mouse Diagnostic Suite
Click any mouse button, scroll the wheel, or move inside the canvas to test hardware switches and polling stability.
No double-click chatter faults detected on mechanical switches.
Frequently Asked Questions (Mouse Double Click & Switch Chatter Diagnostic Tool)
10-Item Technical FAQ & PointerEvent Telemetry Troubleshooting
What is mouse switch chatter (double clicking)?
Switch chatter occurs when a single physical mouse click registers multiple clicks within milliseconds due to oxidized metal leaf contacts.
How does the double click test detect faulty switches?
Logs microsecond timestamp deltas between click release and immediate re-press (t_delta <= 35ms), flagging chatter defects.
Which mouse switch types suffer from double clicking?
Mechanical switches (Omron, Huano, TTC) are prone to oxidation double-clicking; optical switches are immune to mechanical chatter.
Can dust or humidity cause mouse double clicks?
Yes, humidity oxidizes contact leaves and dust prevents clean metal closure, causing erratic electrical signals.
How do I fix a double clicking mouse switch?
Fixes include blowing compressed air into microswitches, applying 99% isopropyl alcohol, re-soldering new switches, or upgrading to optical mice.
Can software debounce delay fix mouse double-clicking?
Yes, increasing software debounce delay in mouse vendor software filters chatter, though it adds minor click latency.
Why do optical mouse switches not double-click?
Optical switches break an infrared light beam instead of making metallic contact, eliminating mechanical contact bounce.
Does this double click test work with side buttons (MB4 & MB5)?
Yes, all 5 mouse buttons—LMB, RMB, MMB, MB4, MB5—are tested for switch chatter.
What is the recommended double click testing time?
Perform 50-100 rapid clicks per button to reliably catch intermittent switch bounce faults.
How do I export my mouse switch health report?
