I have a simple circuit switching activating a 110V timer but would like to show an LED ON indicator at the switch SW when the switch is closed, I can do this easely enough if I run the wire from the LED to ground but this means I need a ground nearby, so my questions is it possible to place the LED in PARALLEL with a resistance R so that when the switch is closed the LED lights up !.
I only want to run 2 wires to/from my switch hence the problem. if I put my LED in series with the circuit it doesn't work if I put my LED across the switch it works in reverse IE the LED is on when the switch is open.
This must be a simple problem can anyone help ?
LED is 110V AC
