I need to make a circuit with 2 leds, 1 green 1 red.
If the current flows, green led will light up, if there is a break in the circuit (open circuit) it will light up another led as red. I don't know how to add the red led and make it light up when both switches in parallel are off. I have no clue how to do this without using a 3rd switch that says close if both switches are open. Help? I've heard of mosfets and spdt but I don't understand them. If someone could draw a beginner schematic it would be great.
