Latching Relay Diagram Circuit. 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.
The switching will be done with a latching relay. The diagram above shows how such a relay can be used to make a latching relay circuit. The diagram of its pins is here.
The relay remembers which switch was pressed last.
Top wiring permanent magnet latching lighting contactors. This creates a basic memory function. In these circuits the set switch is any normally open switch or relay contact such as an mrd1 train detector. The two schematic wiring diagrams below show how to wire an electrically latching relay circuit.
