Bistable relays – Energy-efficient and reliable switching

Bistable relays can be used to switch applications in a reliable and energy-saving manner. They retain their switched position if supply voltage fails, preventing loss of information on the current switching status. Bistable relays allow for two stable switch positions even when powered down. In comparison to monostable relays, just a short switching impulse of a few milliseconds is enough to switch the relay into a defined switch position. Only a low nominal power level is required. This saves energy and reduces heat generation. In addition, the relays have high vibration and shock resistance. The bistable relay OB 5623 with forcibly guided contacts was developed for special, safety-related applications such as in railway and signal technology.
