Press any key to test if your keyboard is working properly
This keyboard tester helps you check if all keys on your keyboard are working properly. Press each key to see it light up green. This is especially useful for testing new keyboards, diagnosing issues, or verifying repairs.
• All Keys Register: Each key should light up when pressed
• No Stuck Keys: Keys should return to normal color when released
• Consistent Response: Multiple presses should work reliably
• Special Keys: Test modifier keys (Shift, Ctrl, Alt) and function keys
• Arrow Keys: Ensure all directional keys work
1. Keys Not Registering: May indicate switch failure or connection issues
2. Double Typing: One press registers multiple times - worn switches
3. Stuck Keys: Key stays pressed or repeats - debris or mechanical failure
4. Intermittent Response: Sometimes works, sometimes doesn't - loose connection
5. Ghosting: Pressing multiple keys causes unwanted key presses
• Mechanical: Individual switches, tactile feedback, more durable
• Membrane: Rubber dome under keys, quieter, less expensive
• Scissor Switch: Low profile, found in laptops
• Optical: Light-based actuation, very fast response
• Hall Effect: Magnetic sensing, adjustable actuation point
