I am trying to detect when a switch is closed to trigger a relay that will then power the circuit. I cannot seem to utilize the switch for the dual purpose.
I have a power relay (12v) that is before a switch that then turns on relays. I want to turn on the power relay when I detect the switch is turned on - thus providing 12v power through the switch and to the relays.
This is part of a bigger project. The power relay will be turned on and off via a transistor and when detecting the closure of the switch, I cannot put 12v on the line - do not want the relays to energize - that is where the power relay comes in.
Below is the drawing for the configuration - i cannot change this - seems that I am just over-thinking this whole thing. I appreciate any comments.
Thank you.
