Abstract

See full text

The disclosure relates to a circuit arrangement for actuating a bistable relay including a relay coil of the bistable relay being arranged in a series circuit with a capacitor, wherein the series circuit is connected to a supply voltage (V+) via a first semiconductor switch for switching on the bistable relay and is short-circuited through a second semiconductor switch for switching off the bistable relay. The circuit arrangement includes at least one voltage regulator configured to regulate the voltage present at the relay coil of the bistable relay such that a preset voltage is not exceeded.
