Bistable relays, also known as latching relays, are a type of relay switch with two stable states: a "set" state and a "reset" state. Unlike standard relays that need continuous power to remain in a certain position, bistable relays only require power to switch between these two states. Once switched, they maintain their state without needing a continuous power supply, making them highly efficient and reliable for a variety of applications.

    In modern electrical systems, the importance of bistable relays cannot be overstated. They play a crucial role in reducing power consumption, enhancing reliability, and ensuring system stability. Their unique design allows them to perform tasks typically requiring much more energy-efficiently. These characteristics make bistable relays especially valuable in environments where low energy consumption is a top priority, such as in smart grids, energy-saving devices, and automated systems.
