I am looking for a little help finding a combinaiton power switch with a relay. Here is my situation if you like easy puzzles. I have a set of photo eyes that send out a 12v signal to a 12v-120v relay that activate a pair of electromagnetic magnets everytime the beam on the eyes are broken. My goal is to find a relay/switch that will activate the magnets the first time the beam is broken, but will open the circuit and not allow the magnets to receive power again until a switch is manually activated, kinda like a circuit breaker. I would prefer for the switch to be lighted so I can tell when the system is ready. Thank you for your help...
