These optical switches limited to mechanical keyboards that support optical switches, so can't interchange for mechanical MX switches. The bottom is different structure.

Optical has a shallower total key travel than typical mechanical switches so that it could enhance speed.

The absence of solder on the switches and the non-mechanical actuation should contribute to longer-lasting switches, and it has no pins, you no longer have to worry about the damage the switch during hot-swappable with others switch.

Gateron switches are smoother and have a slightly higher actuation point than Cherry MX Switches.This optical switch is specially built for KB-64 to meet your various needs.
