I never see in diagrams of relay wiring where the smaller power that runs through a switch or sensor is obtained. I'd like to use the same power source for running the large load and the control circuit. Is is possible to tap off and reduce the voltage and current from a "high power" (120VAC to 12VDC, 1-2A ) transformer with resistor(s) to the point here it will not damage a reed switch or low voltage sensor?
