Setup Guide
1. Installing Switches and Keycaps
The GMK104 is a barebones kit, meaning switches and keycaps are not pre-installed. You will need to purchase compatible 3-pin or 5-pin mechanical switches and keycaps separately.
- Carefully align each mechanical switch with the hot-swap sockets on the PCB.
- Press down firmly until the switch clicks into place. Ensure the pins are straight to avoid bending.
- Once all switches are installed, place your desired keycaps onto the switches. Use the provided keycap puller for easy installation and removal.

Maintenance
