Mouse Double Click Test

This mouse double click test shows whether your switch fires twice per press. Single-click slowly inside the box. Every click shows the gap since the previous one; anything faster than the threshold lights up coral because no human clicks that fast on purpose.

    Diagnose a double-click fault in under a minute

    1. 1. Click slowly, ten times

      Press once per second. Slow clicks make it obvious when the switch adds an extra one.

    2. 2. Watch for coral

      A coral interval means two clicks landed faster than the threshold. One in fifty is noise; one in ten is a worn switch.

    3. 3. Try every button

      Switch to the home page button test and repeat with the right and middle buttons; faults are usually on the most used switch.

    Why this double-click checker is trustworthy

    Adjustable threshold

    Pick 50, 80 or 120 ms depending on how strict you want to be. 80 ms is faster than any intentional human double-click.

    Interval history

    The last twelve gaps stay on screen so you can see whether faults cluster or appear randomly.

    Plain-language verdict

    After ten clicks the tool tells you healthy, occasional bounce, or worn switch.

    Timing is measured with the browser's performance clock and never leaves your tab.

    Understand the vocabulary of switch failure

    Switch bounce
    The metal contacts inside a micro-switch vibrate on contact and briefly reconnect, producing a second click.
    Debounce
    Firmware delay that ignores presses too soon after the last. It masks bounce until the switch degrades past it.
    Phantom click
    A click the mouse reports that you did not make. Double-click faults are phantom clicks within milliseconds of a real one.
    Switch rating
    Manufacturer life expectancy, such as 20 million clicks. Oxidation often ends a switch well before that number.

    Double-click fault questions

    My mouse is new and already shows faults. Why?

    Some new switches have an early-life bounce. Claim warranty rather than waiting; it usually gets worse.

    Can I fix a double-clicking mouse without opening it?

    Sometimes. Blow compressed air into the gap around the button and press it fifty times. If faults persist, the switch needs replacing.

    Does Windows double-click speed affect the test?

    No. The test measures the raw interval between presses and ignores the operating system's double-click setting.

    Why 80 ms?

    Elite clickers peak near 15 clicks per second, about 66 ms apart. 80 ms allows for that and still catches almost every bounce.

    Fix what the test found

    Faults on one button only

    That switch is worn. Replacement switches cost a few dollars and need basic soldering, or claim warranty.

    Faults on every button

    Firmware or driver problem, not hardware. Update the mouse firmware and remove third-party mouse utilities.

    Occasional fault, under five percent

    Clean the switch with compressed air and retest in a week. Early bounce often stabilises after cleaning.

    Drags release on their own

    That is the same fault during a hold. Run the hold and drag test to confirm.
