Professional Double-Click Test Tool Features

📖 Introduction:

Visual Feedback

Distinguish different click types through color changes: light blue for single click, green for normal double-click, red for faulty double-click. Data panel synchronously highlights corresponding button areas.

Color coding: Single click(blue), Normal double-click(green), Faulty double-click(red)

Advanced Double-Click Detection

Comprehensively detect all mouse button functions with three-level counting: total clicks, normal double-clicks (80-500ms), and faulty double-clicks (<80ms). Real-time identification of button degradation.

Tip: Faulty double-click count indicates hardware switch issues.

Adjustable Sensitivity Threshold

Customize faulty double-click detection threshold (50-150ms) to match your mouse type. Gaming mice may require stricter settings for accurate detection.

Adjust the slider to fine-tune detection sensitivity.

Comprehensive Button Testing

Test all 5 standard mouse buttons: left, right, middle, and two side buttons (B4/B5). Many users overlook side buttons which can also develop faults over time.

Tip: All mechanical switches can develop double-click issues.

Real-time Event Log

Record timestamp and detailed information of all mouse operations, including click intervals, button state changes, and double-click events, facilitating problem diagnosis and analysis.

Log displays up to 20 latest records with timing information.

Professional Diagnostic Insights

Get detailed insights into mouse health. High faulty double-click count indicates switch degradation, helping you decide when maintenance or replacement is needed.

Use the threshold slider to customize detection for your specific mouse.

Frequently Asked Questions (FAQ)

How to detect mouse double-click faults?

Click each mouse button normally 50-100 times while monitoring the counters. If the "Faulty Double Clicks" count increases when you're only clicking once, it indicates a hardware issue. The tool automatically detects clicks with intervals less than the threshold (default 80ms) as faulty double-clicks.

What is the difference between double-click and faulty double-click?

A normal double-click is two intentional clicks within 80-500ms interval. A faulty double-click occurs when a single physical press registers as two clicks due to switch bounce, typically with intervals less than 80ms. The former is intentional user behavior, the latter indicates hardware degradation.

How to adjust the detection sensitivity?

Use the threshold slider below the mouse visualizer. Lower values (50-70ms) make detection stricter, suitable for gaming mice. Higher values (100-150ms) make detection more lenient. The default 80ms works for most standard mice.

Why does my mouse have double-click issues?

Double-click faults are usually caused by:

  • Mechanical switch wear from heavy use
  • Dust accumulation inside the switch
  • Oxidation of switch contacts
  • Manufacturing defects in the micro-switch

Which mouse brands are most prone to double-click issues?

While any mechanical switch mouse can develop this issue, it's commonly reported in:

  • Logitech gaming mice
  • Razer optical and mechanical switches
  • SteelSeries gaming mice
  • Any mouse with Omron or similar mechanical switches

This is due to the specific switch models used, not necessarily brand quality.

How to know if my mouse needs replacement?

Consider replacing your mouse if:

  • 1) Faulty double-click count is consistently high on primary buttons;
  • 2) Buttons become unresponsive or require excessive force;
  • 3) Issues persist after cleaning and basic troubleshooting;
  • 4) The problem affects your productivity or gaming performance.

This tool helps you make an informed decision by quantifying the issue.

How does double-click detection work technically?

The tool uses JavaScript to track mouse down/up events with millisecond precision. When a button press is detected, it checks the time since the last press of the same button. If the interval is less than the faulty threshold (default 80ms), it counts as a faulty double-click. If between 80-500ms, it's a normal double-click. The algorithm handles all 5 mouse buttons independently.

Can wireless mice be tested with this tool?

Yes, this tool works with both wired and wireless mice. Ensure your wireless mouse is properly connected and has sufficient battery. Some wireless mice may have different switch characteristics, so adjust the threshold slider if needed.
