About Double Click Tester

Hardware-grade mouse switch bounce & debounce diagnostics in your browser.

Our Mission

Unintended double clicking caused by worn-out mechanical microswitches is one of the most frustrating hardware issues facing gamers, esports competitors, and digital professionals. Our mission at DoubleClickTesting.com is to provide a zero-install, microsecond-accurate diagnostic suite that helps users pinpoint switch degradation, test debounce thresholds, and generate clean proof for warranty (RMA) claims.

Microsecond Precision

Utilizes native browser performance.now() timing attached to low-level mousedown events to measure millisecond click gaps without OS queue delays.

Zero Dependencies

Built with Vanilla JavaScript, static Astro SSG, and Tailwind CSS v4 to ensure instant 100ms load speeds with zero third-party tracking scripts.

Why Mechanical Switches Double Click

Traditional mechanical microswitches (such as Omron 20M, Kailh GM 8.0, or Huano Blue Shell) rely on a thin metallic leaf spring to form an electrical circuit upon pressing. Over millions of clicks, physical metal fatigue, surface oxidation, or static electricity cause the contact leaf to vibrate rapidly during a single press—sending two rapid electric signals (often 5ms to 80ms apart) to your PC.
