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 minimizes physical electrical bounce and false double-clicking.

Why Do Mice Start 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
Chatter ResistantOptical switches (Razer Gen-3, Logitech Lightforce) trigger via an infrared light beam rather than electrical metallic contacts, making them far less prone to contact bounce degradation. Hybrid switches (like Lightforce) retain a mechanical click leaf for tactile feel while relying on optics for actuation.
