Mouse Double Click Test
Click inside the box with each mouse button and find out if your mouse is registering double clicks you never made.
Getting ready…
How It Works
Every mouse button sits on a small metal switch. When the switch wears out, its contacts bounce: a single press is reported as press, release, press. Your computer sees a double click.
This test records every press and release inside the box and measures the gap between each release and the next press. Clicking at a normal pace, nobody re-presses a button within 50 ms, so any faster gap is the switch bouncing, not you.
Right-clicks, middle-clicks and the back and forward side buttons all work inside the box, without opening menus or leaving the page. Nothing leaves your device. Wheel jumping when you scroll? The scroll wheel test checks that.
Interpreting Your Result
Click each button at least 10 times at your normal pace, then finish the test. Only buttons with enough clicks are graded, plus any button that has already double clicked.
Zero double clicks is a pass. One is worth a second test: it can be a fluke, or the first sign of a worn switch. Two or more in one test means the switch is failing.
A failing switch usually gets worse. Many mice can be fixed by replacing the switch, and it is often covered by warranty. Raising the double-click speed setting in your operating system does not help, because the bounce is far faster than any setting.
Keyboard typing letters twice? That is the same failure. The keyboard tester catches it on every key, and the stick drift test checks controllers.
Switch passed? See how fast it can go with the click speed test. A failing switch often shows up first when you click quickly.
Frequently Asked Questions
Why does my mouse double click when I click once?
Almost always a worn switch. The metal contacts inside lose their spring, so one press bounces and is read as two clicks. Dust and static can cause the same symptom for a while.
How do I fix a mouse that double clicks?
First confirm it here: if this test finds no double clicks, the cause is a setting, not the mouse. If it does, compressed air into the gap under the button, or a few firm presses, can help for a while. The lasting fix is a new switch, a small soldering repair, or a warranty claim, since worn switches are a well-known defect.
Is it my mouse or my settings?
If this test finds double clicks, it is the hardware: it reads the raw button events, which settings do not change. If the test is clean but double clicks still happen, check the double-click and ClickLock settings in your operating system.
Does this work for the side buttons?
Yes. Back and forward buttons are recorded inside the test box, and the browser will not navigate away while you test them.
