This guide shows how to replace a key switch on a Tofu65 keyboard with hot-swappable sockets. This is done by removing the old switch from the keyboard and replacing it with a new one. No soldering or prior experience is required to replace the switches.
Clean the keycap either by swabbing the inside and outside with a wet cotton swab or submerging the keycap in a small container with warm water for 30 minutes.
Hand/dish soap can be used as well but not necessary.
Dry the keycaps.
DO NOT leave the keycaps in sunlight or else they could warp.
