ABSTRACT:
Circuit arrangements for the control of a bistable relay having a capacitor connected in series with its excitation winding, in which the series connection of coil and capacitor is connected to excitation voltage for the excitation of the relay and simultaneous charging of the capacitor, and, upon absence of excitation voltage, is short-circuitable through a semiconductor switch having its output circuit parallel-connected with the series connection of coil and capacitor, whereby the relay switches back to its starting position.
