The bistable relay, also known as a latching relay, is an electromechanical device that can maintain its state without continuous power. Unlike traditional relays, which require power to keep their contacts either open or closed, bistable relays leverage magnetic or mechanical principles to hold their position once set. This unique capability makes them an essential component in various applications, ranging from industrial automation to consumer electronics. This article delves into the principles behind bistable relays, their advantages, and their diverse applications.
