Double Click Diagnostic
Click normally inside this field to compare intervals. Short intervals are observations, not proof of a faulty switch.
Double Click Test: Short Click Intervals and Possible Switch-Bounce Patterns
Inspect the timing of repeated mouse clicks. Short intervals can suggest an issue but cannot prove mechanical switch bounce.
What this test checks
- Button event accuracy
- Timing, interval, or movement consistency
- Live browser input feedback

How to read the result
Double Click results should be read as browser-captured diagnostics. Strong results are consistent across repeated runs; unusual spikes, missed events, or unstable timing are a sign to compare with the related mouse tools before blaming the hardware.
Use Normal Click Pressure
The best double-click test starts with natural clicking, not forced spam. Normal pressure helps reveal whether the mouse is generating extra clicks that the user did not intend.
Capture Fast Click Intervals
The diagnostic records timing between repeated button events. Very short intervals can indicate switch bounce, worn contacts, or firmware behavior that creates accidental double-clicks.
Read Suspicious Bounce Candidates
The report lists candidate intervals below the threshold so users can see why the verdict changed. This is better for troubleshooting than a hidden pass or fail decision.
Retest After Cleaning Or Changing Switches
Users can run the same double click checker after cleaning the button, changing debounce settings, or replacing switches. A lower suspicious count suggests the problem improved.

What does Double Click measure?
Inspect the timing of repeated mouse clicks. Short intervals can suggest an issue but cannot prove mechanical switch bounce.
Do I need to install anything for Double Click?
No. Double Click runs directly in a modern browser. Some checks may ask for permission when they need camera, microphone, gamepad, pointer lock, touch, or audio output access.
Are results uploaded?
The test runs in your browser and uses local input events or browser hardware APIs for the visible diagnostics.
Why should I run related tests too?
Related tools help separate hardware issues from browser timing, display behavior, input device settings, or permission problems, which makes the final diagnosis more useful.
Detailed Testing Guide
Mouse symptom
This mouse page isolates one input symptom instead of mixing every click, wheel, button, and movement problem into one vague result.
Start with a baseline run before changing device settings. Record any repeated symptom so the next comparison is useful.
Mouse evidence
The useful evidence is browser-visible mouse behavior: button identity, timing, intervals, movement, wheel data, and completion state.
Watch Button event accuracy, Timing, interval, or movement consistency, Live browser input feedback, Read Suspicious Bounce Candidates. These observations come from the browser; they do not reveal hidden firmware or factory calibration data.
Clean test method
Keep the pointer inside the test field, use the same grip, and repeat the same action before judging the mouse.
Keep the test conditions stable. Changing browser, cable, port, lighting, surface, volume, grip, or selected device all at once makes the result harder to trust.
Result reading
Missed clicks, unexpected double events, wrong button labels, scroll jumps, or unstable hold behavior deserve a second focused test.
A repeated pattern matters more than a single spike. When something looks wrong, confirm it with another pass and compare a related tool before deciding the device itself is defective.
Limits and next checks
Move between click speed, button, double-click, scroll, DPI, reaction, and drag dropout pages depending on the symptom.
For a closer comparison, try Mouse Button Test, Left Click Speed Test, Right Click Speed Test, Drag Dropout Test. Keep the same device and connection while you investigate the next symptom.
