How to Wire This Latching Relay - Electrical Engineering How to Wire This Latching Relay. The switching will be done with a latching relay. The diagram of its pins is here: My proposed solution is with a regular non-latching relay (and thus pin numbers may be wrong). If the relay is rated for 120V, then my first attempt would look like this.I don't believe your application can be solved with the components you mention. Either you need switches that give a single pulse or a non-latching relay. My proposed solution is with a regular non-latching relay (and thus pin numbers may be wrong). If the relay is rated for 120V, then my first attempt would look like this. The below is with a non-latching relay though. simulate this circuit – Schematic created using CircuitLab1simulate this circuit – Schematic created using CircuitLab I think this will work. The stop switch (high water level) is trying to apply power to turn the relay on because it is a NC switch. If the start switch (low water level) is operated then power is fully applied to the relay and the start switch is bypassed by one of the relay contacts and this keeps the relay on. This operates the solenoid and it starts "pumping" water. When the top water level is reached the stop switch disables the relay and the system is reset until water level is low enough to close the start switch again. BTW the schematic editor is really coooool1Power neutral connects to A and to one side of your solenoid.
One switch connects to B. The other switch connects to 8.
Power hot connects to either 11 or 21, your choice, and to the other terminal on each of the switches.
The second solenoid wire connects to either 14 (if hot is on 11) or 24 (if hot is on 21), your choice. There should be no requirement for any resistors, provided that the relay can tolerate 120V, 100% duty cycle, on its two actuating terminals.0How does this latch relay work? - Electrical EngineeringResettable latching switches - Electrical EngineeringSee more results 11 Pin Relay Wiring Diagram - Wiring Diagram And Schematics 11 Pin Latching Relay Wiring Diagram Schematic | Wiring Diagram - 9 pin latching relay wiring diagram schematic wiring diagram11 pin relay base diagram all wiring diagram11.
