Frequently Asked Questions (Mechanical Keyboard Switch & Chatter Diagnostic Tool)
10-Item Technical FAQ & USB HID Diagnostic Troubleshooting
What causes mechanical keyboard switch chatter?
Oxidized metallic contact leaves, weak spring tension, or dust contamination cause switch contact leaves to bounce multiple times during a single press.
How does the mechanical switch chatter test detect double typing?
Logs microsecond timestamp deltas between key release and immediate re-press (t_delta <= 35ms), flagging chatter defects.
Which mechanical switches are supported?
Supports Cherry MX, Gateron, Kailh, Outemu, Razer, SteelSeries Apex OmniPoint, and Wooting Lekker magnetic Hall Effect switches.
Can I test hot-swappable PCB switch sockets?
Yes, testing after hot-swapping individual switches verifies whether chatter was caused by the switch stem or PCB socket.
What is switch actuation force and travel distance?
Actuation force (grams) is the physical pressure required to close contacts, while actuation travel (mm) is distance pressed before signal registers.
How do tactile, linear, and clicky switches differ?
Linear switches press smoothly, tactile switches have a tactile bump at actuation, and clicky switches add an audible click mechanism.
How do I clean a chatty mechanical switch without desoldering?
Apply 1-2 drops of 99% isopropyl alcohol into the switch stem while depressed and actuate repeatedly to dissolve contact oxide.
Can software debounce delay fix switch chatter?
Yes, increasing MCU debounce delay settings in QMK/VIA or Windows registry filters chatter, though it adds minor input latency.
What is optical switch technology?
Optical switches break an infrared light beam instead of making metallic contact, completely eliminating mechanical contact chatter.
