- Align the pins of the new 3-pin switch with the holes on the PCB.
- Press the new switch firmly into place until it clicks. Ensure pins are not bent.

Maintenance
- Cleaning: Use a soft brush or compressed air to remove dust and debris from between the keycaps. For deeper cleaning, remove keycaps and wipe them with a damp cloth. Ensure the keyboard is disconnected before cleaning.
