Hello,
I am currently trying to wire aftermarket door lock actuators. The switch I want to use is a single wire. The switch is in a car, so it has a 12v source.
This is where it gets tricky - When the switch is pressed to "Unlock" it closes the circuit and has a resistance of 50 Ohms. The "Lock" side of it has a resistance of around 765 Ohms. My goal is to use relays to trigger 2 separate circuits.
The unlock switch will send the full 12v to a normally closed relay, in order to block the voltage to the "lock" side of it. The unlock pulse will also send the output signal to the door "unlock" mechanism.
However, for the "Lock" side of things, my idea is to use a smaller relay.. Perhaps a 3v or 6v. Something small enough that when the switch is set to "Lock" it is not quite powerful enough to trigger the 12v unlock because of the extra resistance. I am stumped here though because I am not sure whether or not this is the best solution and how to figure out the best way to wire the resistors and relay on the "Lock" side of the switch.
Any help or suggestions is greatly appreciated!
