5.3 Hot-Swappable Switches

The AK820 keyboard features a hot-swappable PCB, allowing you to change mechanical switches without soldering. This feature supports most 3-pin and 5-pin switches available on the market.

1. To remove a switch, use a switch puller tool (not included) to gently grip the switch and pull it straight up.
2. To install a new switch, align the pins of the new switch with the holes on the PCB. Ensure the switch is oriented correctly.
3. Gently press the switch down until it clicks into place. Do not force the switch, as this may bend the pins.
4. Test the new switch to ensure it functions correctly.
