A latching relay is a two-position electrically-actuated switch. It is controlled by two momentary-acting switches or sensors, one that 'sets' the relay, and the other 'resets' the relay. The latching relay maintains its position after the actuating switch has been released, so it performs a basic memory function.. Circuit Diagram of the Latching Relay. Figure 1: Latching Relay Circuit Courtesy of Simon Mugo. The circuit diagram is made up of two push buttons. The push-button B1 is suitable for completing the circuit, while push-button B2 is for breaking the circuit's current flow. The latching relay will energize when pressing the first push-button.

What is a LATCH ??? (Theory & Making of Latch

A circuit diagram of a latching relay will show you the various parts of the relay, like the coil, the contacts, and the electromagnetic field master core, and how they interact with each other. It will also provide a good overview of how the switch works, how it can be triggered, and any other nuances you may need to be aware of.. Latch basically means "to become fixed in a particular state". In Electronics, Latch Circuit is a circuit which locks its output, when a momentarily input trigger signal is applied, and retains that state, even after the input signal is removed. This State will remain indefinitely until the power is reset or some external signal is applied.
