ABSTRACT:
Circuit arrangements for the control of a bistable relay having a capacitor connected in series with the relay coil. The series connection of the coil and the capacitor is connected to an excitation voltage for actuating the relay and simultaneous charging of the capacitor. When the excitation voltage is removed, the series connection is short-circuited through a semiconductor switch, whereby the capacitor is discharged and the relay switched back to its initial position. The bistable relay is thus operated as monostable relay.
