How to Wire This Latching Relay

Posted on Feb 5, 2014

Switch a water solenoid valve using two water level switches, one will be placed at the top of a tank and will be NO (when water level is between full and empty) so that it will send a signal to the relay when the water reaches the top to stop the solenoid. The other switch will be at the bottom of the tank and will be NC so that i

t will send a signal to the relay when the water reaches the bottom of the tank to open the solenoid. What I am asking for is this: on that diagram, where do the switches connect Where does the solenoid valve connect Where does mains power connect Lastly, do I need any resistors on the control side of the circuit
