마우스 클릭 속도 테스트 & 클릭 테스트 — 무료 온라인 진단 도구

To test mouse click functionality, position your cursor over the interactive test pad on MouseClick.org and click any mouse button. The tester immediately detects:

• Left Click (Button 0): Primary action and release timing.
• Right Click (Button 2): Secondary click with browser context menu suppression.
• Middle Click (Button 1): Scroll wheel depression without triggering autoscroll.
• Side Buttons (Buttons 3 & 4): Browser back/forward navigation thumb buttons.

Everything runs 100% locally in your web browser with zero software installation or drivers required. The visualizer displays real-time click counts, press-down and release timestamps, and monitors for missed inputs or stuck switches.

Click latency (input lag) is the millisecond delay between physical switch actuation and the operating system or browser processing the event. You can test latency using our:

• Reaction Time Test: Benchmarks your visual-to-click reflex response in milliseconds.
• Polling Rate Test: Verifies USB sensor report delay (1000Hz = 1.0ms, 4000Hz = 0.25ms, 8000Hz = 0.125ms).

Optical switches (like Razer Optical) eliminate debounce delays, achieving ~0.2ms click latency, whereas mechanical switches typically impose 4ms to 12ms of firmware debounce delay to filter physical contact bounce.

Testing if your mouse is broken: Use our 4-point hardware inspection workflow:

1. Button Test: Verify all buttons actuate without missing clicks or intermittent connection drops.
2. Double-Click Test: Check for contact chatter bounce below 80ms on single clicks.
3. Scroll Wheel Test: Check for jumping or reversed encoder ticks during smooth scrolling.
4. Hold & Drag Test: Verify leaf spring contact does not drop during dragging or selecting files.

Mouse Click Tester Unblocked: Yes! MouseClick.org contains no ads, requires no plugins, and runs 100% locally in browser memory. It is accessible and unblocked on school Chromebooks, library computers, and office networks.

To test mouse middle click, click directly downward on your scroll wheel. On unoptimized websites, this triggers auto-scrolling with an omnidirectional pan cursor. Our tool prevents auto-scroll and registers the discrete button === 1 event, logging middle click state, click count, and hold stability.

Mouse wheel tactile push microswitches (located underneath the wheel axle) are prone to stiffening or failing from dust accumulation. Press the wheel firmly at different angles. If the tester fails to register the middle click or requires excessive force, the switch contact is oxidized or the wheel axle plastic has fatigued.

To test for double-clicking defects, open our dedicated Double-Click Test. Click the test pad in steady single taps 50 to 100 times. A healthy mouse registers exactly one event per finger press with intervals over 120ms.

Testing a double-click mouse involves measuring the millisecond delta between the pointerdown and subsequent pointerup events. The human finger cannot physically click twice in under 50 milliseconds. Any second click registered within 10ms–80ms is conclusive proof of physical microswitch chatter or contact bounce.

When claiming a warranty (RMA) with Logitech, Razer, SteelSeries, or Corsair, manufacturers require proof of switch chatter. On MouseClick.org:

1. Perform 50 single clicks on the Double-Click Test.
2. Wait for red chatter bounce detections to log.
3. Click Export RMA Report in the header to generate a timestamped markdown diagnostics certificate.
4. Attach the log directly to your customer support ticket for fast RMA approval.

How fast can you click? Run the Click Speed Test to measure your Clicks Per Second (CPS) across 1-second, 5-second, 10-second, or 60-second endurance timers.

Different clicking techniques yield dramatically different speed results:

• Normal Clicking: 6 to 9 CPS (clean control, ideal for Valorant & CS2).
• Jitter Clicking: 11 to 14 CPS (forearm muscle vibrations).
• Butterfly Clicking: 15 to 24 CPS (alternating two fingers on wide mouse switches).
• Drag Clicking: 25 to 40+ CPS (friction glide across matte switch textures).
