A latching relay, also known as a bistable relay, is a type of relay that maintains its position after being actuated, even when the power is turned off. Unlike traditional relays that return to their default state once power is cut, latching relays "latch" in one of two positions and require a pulse of current to change state. These relays are widely used in various industrial, commercial, and residential applications for their ability to conserve power and maintain settings without continuous energy supply.
