I'm thinking of using a switch in my car. The switch has 5 leads: +, -, C, NO, and NC. 12 V to the + and - light the LED (brightly). What I would like it to do is light up the LED dimly when the dash lights are on AND light it more brightly when the switch is on.
How would I do this?
Or would it be simpler to have it light up dimly when the switch is off using a resistor between NC and +, and then brightly when the switch is on (direct wire from NO and +)?
I'm thinking this could be a problem because since the device I want to turn off and on will be wired to NO; it will get power from NC (through +) when the switch is off. This wouldn't be good! Is there a way to prevent this? Or perhaps a better way to go about the whole thing (apart from having a switch with 2 LEDs)?
