4.2 Sostituzione dei tasti e degli interruttori
The SK21 Numpad features PBT keycaps that are durable and oil-resistant. If you wish to replace them, use the provided keycap puller to gently remove the existing keycaps. Align the new keycaps with the switch stems and press down firmly until they click into place.
For hot-swappable versions (only for optical switches), use a switch puller to carefully remove switches. Insert new compatible optical switches by aligning the pins with the PCB sockets and pressing down until they are seated.
