What is a Latching Relay ?

Latching Relay Definition

A latching relay is a type of relay that maintains its contact position without continuous power application, allowing for efficient control of circuits.

Circuit Diagram

The latching relay circuit diagram shows how Button-1 and Button-2 control the energizing and de-energizing of the relay, respectively.

Operation Mechanism

By pressing Button-1, the relay is energized and remains so even after the button is released, until Button-2 is pressed.

Efficiency and Use

Latching relays are energy efficient as they require power only for changing states, not for maintaining them.

Practical Application

They are commonly used in setups requiring the circuit to remain active without continuous power, such as home lighting systems and industrial conveyors.
