Why Mechanical Mouse Switches Suffer from Double-Click Faults
Mechanical microswitches rely on copper alloy leaf springs. Low-voltage signals in modern wireless mice accelerate contact oxidation.

Double-Click Health Guidelines
0 double-click faults over 50 clicks indicates a healthy switch. Any single-click registering under 80ms confirms switch bounce failure.
How to Get Started
Just three steps to run a complete controller test and understand your controller's health status.
01
Connect Controller
Connect your controller to your computer via USB cable or Bluetooth. If the browser doesn't respond, press any button on the controller to activate the connection.
02
Button Detection
Press each button in the visual interface and confirm the corresponding area lights up on screen. This helps troubleshoot unresponsive or double-clicking buttons.
03
Sticks & Vibration
Rotate the sticks to check linearity and drift issues; click the vibration test button to feel if the left and right motor feedback is working properly.

Frequently Asked Questions
Everything you need to know about testing your controller.
How do I test if my mouse has a double-clicking fault?
Single-click the test target box 50 to 100 times slowly. If the counter registers a double-click fault (interval < 80ms), your mouse switch has mechanical contact bounce failure.
What causes mouse double-clicking issues?
Traditional mechanical microswitches (Omron 20M/50M) use metallic leaf springs that oxidize or lose tension over time, causing electrical contact bouncing that registers as two rapid clicks.
Do optical mouse switches prevent double-clicking?
Yes! Optical mouse switches (Razer Optical, Light Strike) use light beam actuation instead of physical metallic contacts, permanently eliminating double-click faults.
How this test works & its limits
- This test reads your controller through the browser's standard Gamepad API — no drivers, no installs, nothing leaves your device.
- Readings depend on connection mode: Bluetooth reports at lower rates than USB. Compare like-for-like (wired vs wired).
- We measure the input reaching the browser — display lag and game-engine queues are outside this test's view.
- A clean reading now does not guarantee no drift in-game: deadzones differ per game, and wear develops over time. Use the Drift Timeline to track yours.
- This is a diagnostic, not a hardware-lab certification. For repair or RMA decisions, confirm with a second run or second tool.
