Relay Latching Circuit Diagram. Current limiting resistors must be used at the bases of. All connection of components have to be done in exact same manner as shown in the picture.
In this article were going to look at both the driver circuit for a latching relay and the software considerations. When the push to make button is pressed 12v goes across the coil energising the relay. Circuit diagram of latching circuit is simple and can be easily built.
The relay remembers which button was pressed last see description below.
The relay remembers which button was pressed last see description below. The diagram above shows how such a relay can be used to make a latching relay circuit. Current limiting resistors must be used at the bases of. 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.
