I need help from the mighty electronics Gurus.
I need to build a switch that will supply a constant 12v to multiple sources when it receives a 12v 'on' signal and turn off power when the 'on' signal goes away.
I thought about using an automotive StartUp/ShutDown controller, but the circuit is more complicated than I need. This is not to power a pc, but rather other accessories in my car.
Any help is appreciated, if any more info is need I will provide it
You can use a spst or spdt relay for this. Any bog-standard ordinary automotive relay (they are usually spdt) will do exactly what you describe.
