Mouse Click Test — Free Online Mouse Diagnostics & Double-Click Tester
Normal Contact Stability
Click steadily to check for hardware bouncing. Switches with degraded metal leaf springs register double-clicks under 30ms.
Move your mouse smoothly inside the arena. Browsers throttle standard events, but raw hardware input events are sampled directly.
Browser-Based Mouse Diagnostics: Real-Time Switch & Sensor Telemetry
The MouseClick.org testing arena provides deep hardware telemetry without requiring driver installations or background companion apps. Built entirely on the HTML5 Pointer Events API and Web Audio API, every physical switch actuation, wheel notch, and drag vector is sampled directly in your browser with zero input buffering.
5-Button Independent State Tracking
Isolates primary left clicks (Button 0), right clicks with browser context menu suppression (Button 2), scroll wheel downward depression (Button 1), and side thumb navigation switches (Buttons 3 & 4). Each button tracks cumulative click volume, real-time press state, and down/up release delta timestamps.
Sub-80ms Contact Bounce Analysis
Physical copper leaf springs vibrate when worn, causing single clicks to register two electrical signals. The diagnostic engine monitors inter-click intervals (Δt); any consecutive signals under your configured debounce threshold trigger a red chatter warning and exportable RMA certificate.
Scroll Direction & Velocity Telemetry
Inspects rotary optical and mechanical encoders for jumping, stuttering, or reversed scrolling. Analyzes 2-bit Gray code detent ticks to expose dust contamination on conductive wiper traces or loose wheel axles.
Sustained Contact Dropout Inspection
Verifies that microswitches maintain solid electrical contact under continuous finger pressure. Flags inadvertent file dropouts caused by oxidized contacts or fatigued leaf springs during desktop drag-and-drop operations.
