Latching Relay Wiring Diagram. In these circuits the set switch is any normally open switch or relay contact such as an mrd1 train detector. And to the other terminal on each of the switches.
It shows the components of the circuit as simplified shapes and the capacity and signal connections in the midst of the devices. They are easy to understand you can see them working and they are still in use today in many many systems to switch voltage into circuits to. When the push to make button is pressed 12v goes across the coil energising the relay.
The diagram above shows how such a relay can be used to make a latching relay circuit.
When the push to make button is pressed 12v goes across the coil energising the relay. The circuit has two buttons one is a push to make which closes when pressed but is otherwise open and the other is a push to break which opens when pressed but is otherwise closed. The reset switch is any normally closed switch or relay contact. And to the other terminal on each of the switches.
