JadMaktabiThanks for the reply! So does that mean if one of my key switches led breaks, can I just replace that with another switch and it will work again?
naokuronaoNo. LEDs are on the pcb never on the switch. On this particular pcb, the LEDs do not pass through the switch housing, which is why you can replace the switch without soldering. If an LEDs goes out on this pcb, you need to unsolder, then solder in a new one. Most likely you would ask MD for a new pcb.
