3.1 Installing Mechanical Switches

The GK21S features hot-swappable Kailh connectors, allowing for easy installation and removal of mechanical switches without soldering. Ensure your switches are compatible with MX-style sockets (3-pin or 5-pin).

1. Align the pins of the mechanical switch with the corresponding holes on the PCB.
2. Gently push the switch straight down until it clicks into place. Do not force the switch if it does not align easily, as this may bend the pins.
3. Repeat for all 21 switch positions.
