Great switches, just drill a hole - it may be necessary to file the hole a bit where the tabs are, but don't over do it or the switch may be loose. If you have a looseness problem a dab of 5 minute epoxy will keep it steady. Like someone commented, the led light needs to be connected to the negative/ground terminal, it may be too bright, my fix was a 1000 ohm 5 watt resistor. Just run all your switches if they have a led light through this one resistor. 5 watts is overkill, but it was laying around, and anything around 500 to 2000 ohms should work. I'm very pleased with these switches.
