Latching relays are a type of electromagnetic relay designed to retain their switched state without continuous power. Unlike regular relays that return to their default state once power is removed, latching relays "latch" in a position and remain there until actuated by a separate pulse. This unique characteristic allows them to be energy-efficient, as they do not consume power once set, which is crucial in many modern applications where energy conservation is paramount.

    Latching relays are widely used in various industries, including telecommunication systems, energy distribution, automotive electronics, and smart home systems. Their ability to maintain states over extended periods without drawing power makes them a popular choice for applications that need to switch between two or more states without constant monitoring or power usage.
