Low Voltage Switchgear

Bistable switches are mainly used for switching of lighting. They are also becoming an alterna-tive to installation relays and contactors. At remote switching of lighting, a parallel connection of push-buttons is used. In this way, a number of conductors is smaller than in case of connection with cross-point and reversing switches. Owing to pulse control of a bistable switch, continuous control current does not flow through the switch coil, which results in considerable saving of electric energy.
