Make deliberate single clicks with one mouse button. GearCheck Lab times consecutive presses of that same button and flags intervals below your chosen suspected-chatter threshold, helping you reproduce unwanted double-click symptoms without treating one fast event as proof of a failed switch.
Select one logical mouse button and leave the threshold at 60 ms for the first comparison.
Make 30 slow, deliberate single clicks. Do not intentionally double-click or chase a high click rate.
Record the number of valid intervals, suspected repeats, shortest interval, threshold, button and test environment.
Reset and complete three sessions with the same button, pace, browser and connection.
Repeat on another mouse button. If flags persist, compare another USB port or receiver position, browser, and computer while changing one variable at a time.
Compare repeated sessions, not one dramatic number. A pattern that follows one physical switch across environments is stronger evidence than an isolated browser interval.
Interpret the valid interval sample
The summary starts after 19 valid same-button intervals. A valid interval is formed only by consecutive uninterrupted presses of the selected mouse button. Touch, pen, other buttons, hidden tabs, focus loss and non-monotonic timestamps do not become evidence.
No flags: no browser-visible interval fell below the chosen threshold in that session; intermittent symptoms can still need more runs.
One or two flags: retest before drawing a conclusion.
Repeated flags: the symptom is reproducible in this browser sample if your physical actions were deliberate single clicks.
Interrupted warning: the previous pairing baseline was discarded; collected valid intervals remain, and the next press begins a new pair.
Worked interval examples
0 of 24 below 60 ms: no short intervals were observed in that run. Repeat if the unwanted double click is intermittent.
1 of 24 below 60 ms: treat it as an isolated flag and repeat the same session rather than labelling the switch failed.
6 of 24 below 60 ms: repeated short browser intervals deserve comparison with another button and environment.
4 of 24 after changing to 90 ms: this is not comparable with a 60 ms run unless the threshold change is recorded; the page reclassifies the same sample when the slider moves.
Troubleshoot repeated short intervals
Disable click macros, turbo modes, remapping and accessibility repeat features temporarily.
Try a wired connection or fresh battery, then change USB port or receiver position.
Compare main and secondary buttons at the same threshold and deliberate pace.
Repeat in another current desktop browser and another computer if available.
If the pattern follows one physical switch across environments, consult the manufacturer warranty or a qualified repairer before opening hardware.
Limits of browser switch timing
The page sees Pointer Events after the mouse firmware, USB or wireless link, driver, operating system and browser have processed them. It cannot inspect electrical bounce, debounce firmware, switch travel, USB packets or end-to-end latency directly.
Timer precision can be reduced, events can be coalesced or delayed, logical button mappings can change, and deliberate human clicking is never perfectly uniform. The adjustable threshold is a transparent heuristic, not a universal pass line.
Privacy and result scope
Click intervals, counts and classifications are calculated in the page and cleared by reset or reload. This tool does not upload the diagnostic sample. GearCheck Lab still serves normal site resources and may use consented analytics under the Privacy policy.
Results describe browser-visible input from one session. They are troubleshooting evidence, not hardware certification, a warranty decision or proof of the electrical cause.
It records valid same-button pointer-down intervals that reach the browser and flags intervals below your selected heuristic threshold. Repeated flags during deliberate single clicks can help reproduce a chatter symptom, but they do not certify an electrical switch fault.
Does one short interval mean the mouse switch is broken?
No. One isolated short interval can come from technique, browser timing, software or an accidental fast press. Reset and repeat multiple deliberate single-click sessions before comparing another button, browser or computer.
What threshold should I use for switch chatter?
Start with the default 60 ms only as a comparison aid. There is no universal browser cutoff for mechanical debounce failure. Keep the threshold unchanged while comparing repeat sessions, then record any threshold change with the result.
Why not rely on the browser double-click event?
A browser double-click event already applies operating-system and browser interpretation. This diagnostic compares same-button pointer-down spacing so you can see the measured intervals and the chosen heuristic separately.
Can I test side buttons and swapped mouse buttons?
The page offers logical browser button codes, but operating-system settings can swap main and secondary actions, and browsers or vendor software may intercept back and forward buttons. Confirm which on-page button responds before interpreting a run.
Does the diagnostic send my click intervals anywhere?
The interval sample is processed in this page and is cleared by reset or reload. The site still makes ordinary web requests and may send consented analytics as described in the Privacy page; the diagnostic result itself is not uploaded by this tool.
