Help!
I have some DPST rocker switches with dual LEDs. 8 pins per switch. Eventually figured out that the top 2 pins provide power and earth to the upper LED, and the bottom two pins go to the lower LED that illuminates when the central pins are closed, connecting the lead into and out of the switch.
Ive tested these with a power supply across the switch, and they work as desired. I then asked someone if the same switch would be ok for the battery contactor, that is switched to ground.
I assumed it would be fine... electrons can't know at what point they are in between the battery +ve and battery negative, so why would it matter if the switch was on the negative side of the 'device' or the positive side... but the guys I purchased the switch from said it wouldn't work as the lead into the switch isn't a red positive, so it cant be 'jumped' to the positive side of the LED. I just don't get it... an I being dim?? If I am, how do I get the illuminated switch to work when the battery master switch is turned on?
