Every detail matters, so we make the K4 Version 3 hot-swappable for your personalized typing experience. The hot-swappable sockets are mounted on the PCB, so you can hot-swap every switch on the K4 Version 3 with almost all of the 3pin and 5pin MX style mechanical switches on the market (including Cherry, Gateron, Kailh, Panda, etc.) without soldering.
