Electromechanical Bistable Relay PSU

Contact multiplier relay with 6/14 double interruption contacts

The bistable relays are mainly used for remote and automatic controls where there is often a need for contactors which have two stable contact positions, even in the dead state.

The application of alternate control pulses to the coils cause the contacts to change from the one state to the other. If the supply is interrupted, the contacts remain in their previous position, even when the voltage is restored. The contacts are arranged symmetrically on both sides of relay coil and armature assembly in two stacks.
