A latching relay, often referred to as a bistable relay, is a crucial electrical component that has found widespread use in various applications due to its ability to retain its position even after the control power is removed. Unlike traditional relays, which require continuous power to maintain their state, a latching relay maintains its position by "latching" onto one of two states, either normally open or normally closed, with a simple pulse. This feature makes it more energy-efficient and reliable for long-term operation in diverse environments.
