Button Function Test + Side Button Test + Click Test
📖 Introduction:
Distinguish different operation 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.
Comprehensively detect all mouse button functions, including left, right, middle and side buttons. Real-time display of press and release counts, accurately identifying button sticking or failure issues.
Automatically identify double-click operations, distinguishing normal double-clicks (200-500ms) from faulty double-clicks (<80ms). Abnormal double-click intervals may indicate button mechanical failure or micro-switch aging.
Detect mouse wheel up/down scrolling function, independently counting scroll up and scroll down actions. Suitable for testing wheel encoder performance and scrolling sensitivity.
Record timestamp and detailed information of all mouse operations, including button state changes, wheel actions, and double-click events, facilitating problem diagnosis and analysis.
Test area border color reflects test status in real-time: blue(active), light blue(testing), green(double-click detected), red(fault).
Press any button on the mouse, the corresponding press counter on the right will increase. When you release the button, the release counter will also increase. If the counter doesn't change, the button may be faulty. Normal buttons should respond both when pressed and released.
Press the mouse side buttons (usually marked B4 and B5), the corresponding side button press and release counters will increase. If the counters don't change, the side buttons may be faulty. Side buttons are usually located on the left side of the mouse, used for web forward/back or custom functions.
Press count tracks how many times you've pressed the button. Release count tracks how many times you've released the button. For normal mouse operation, these two numbers should match when you release the button. If they don't match, it may indicate a stuck button or abnormal release. Significantly different counts may indicate mechanical issues with the button.
This situation is likely caused by abnormal button contact, which may result from:
Independent counting of scroll up and scroll down helps diagnose specific wheel encoder issues. For example, if only scroll up count increases while scroll down doesn't respond, it may indicate poor contact or damage in one direction of the encoder.
Consider replacing the mouse if the following situations occur:
This tool can help you systematically diagnose these issues.
