4. Setup and Assembly
This keyboard kit requires assembly of switches and keycaps. Please follow these steps carefully:
4.1 Installing Switches
- Ensure the keyboard kit is disconnected from any power source.
- Carefully align the pins of your chosen mechanical switch with the hot-swap sockets on the PCB.
- Important: Before inserting, check if the switch pins are bent. Straighten any bent pins gently with tweezers if necessary.
- Insert the switch vertically into the hot-swappable shaft holder until it clicks into place. Do not force the switch if it doesn't go in smoothly, as this may damage the pins or the socket.
- Repeat for all 84 switch positions.
