I tried one of these Illuminated 3PDT Breakout Boards with a Ring LED 3PDT. It didn't work at first. Took me a while to figure out that I had to ALSO put an LED in the A-K terminals of the PCB presumably to complete the circuit. Maybe a jumper would also work. Anyway, I don't necessarily understand why. Would be nice if there was documentation to say as much.
