Mouse Double Click Test
Measure time intervals between clicks to detect degraded switch contacts and debounce bounce faults across Left, Middle, and Right buttons.

Click single clicks naturally. Sub-80ms events are isolated into severe leaf bounce (<30ms) vs. rapid human jitter.
Microswitch Debounce & Double-Click Vulnerability
Comparison of optical vs mechanical switches, illustrating how infrared actuation eliminates physical electrical bounce and false double-clicking.

Mechanical Contact Oxidation
Microswitch WearTraditional mechanical switches (Omron, Kailh, Huano) rely on metal leaf springs. Over millions of actuations, oxidation and metal fatigue create microscopic electrical chatter on contact release.
Debounce Delay Algorithm
Firmware FilterMouse firmware applies a debounce timer (typically 4ms to 12ms). If physical contact bounce exceeds this window, the controller reports two distinct clicks to the operating system.
Human vs Switch Bounce
< 80ms FaultPhysical finger speed rarely produces consecutive clicks below 60–80ms on a single button. Intervals faster than 50–80ms on a single press almost always indicate mechanical switch failure.
Optical Switches
Immune to ChatterOptical switches (Razer Gen-3, Logitech Lightforce) trigger via an infrared light beam rather than electrical contacts, making unintended double-clicking physically impossible.
Double-Click Switch Test Frequently Asked Questions
- Click the test target repeatedly. If a single physical press triggers two registered clicks with a switch debounce time under 80 milliseconds, your mechanical switch is experiencing metallic leaf chatter.
- Over time, mechanical metallic contact leaves oxidize and lose spring tension, causing electrical bounce (chatter) upon contact release.
- Yes. Optical switches use an infrared light beam instead of physical metallic contacts to detect clicks, making them physically immune to double-click chatter.
