Optical Red Switch Test

Optical Red switches use a light beam instead of metal contacts to register key presses. An infrared LED and sensor detect when the stem interrupts the beam, triggering actuation instantly with zero physical debounce. This means faster response, no contact bounce, and a 100 million keystroke lifespan — double that of Cherry MX.
