Latching relays or bistable switches are switching devices with two stable states for switching of all kind of electric loads. Those switches operate without power consumption in operating switch-on position and with a very small consumption per pole.

Are you looking for savings in electric energy? Replace installation relays and contactors with latching relays. At remote switching of lighting, a parallel connection of pushbuttons is used. In this way, a number of conductors is smaller than in a case of connection with cross-point and reversing switches. Because of the pulse control of a latching relay, continuous control current does not flow through the switch coil, which results in a considerable saving of electric energy.
