SIP sockets allow for changing LEDS without re-soldering LEDS. By installing the SIP socket to the switch, then soldering the sockets instead of the LEDS onto the PCB, you can switch out the colour of the LEDS on the switch without resoldering anything.

2 per switch = Enough for 100 Switches (up to TKL/96 boards)
