Mechanical Keyboard Architecture: Switches, Debouncing & Key Rollover
Whether troubleshooting an unresponsive switch, testing custom firmware, or verifying anti-ghosting capabilities on gaming peripherals, comprehensive keyboard testing confirms hardware integrity.
Key Rollover: 6KRO vs. NKRO (N-Key Rollover)
Standard office keyboards use a matrix of contact membranes where pressing more than 3 adjacent keys simultaneously causes 'ghosting' (unregistered or phantom keypresses). Gaming and custom mechanical keyboards incorporate diodes at each switch, providing true NKRO (N-Key Rollover) where every simultaneous press registers cleanly.
