ABSTRACT:
An electric supply circuit is provided for a switch actuating device containing an actuator, an electromagnetic drive for displacing the actuator from a first switching position to a second switching position, and a mechanical return device for returning the actuator from the second switching position to the first switching position. A magnetic fixing unit is provided for fixing the actuator in the second switching position and an electromagnetic releasing device is provided for releasing the fixation. The electric supply device contains a first capacitor electrically connectable to the electromagnetic drive and used for supplying electric power thereto and a second capacitor that is electrically connectable to the releasing device and supplies electric power thereto for releasing the fixation. An electric switchable connection is provided between the first and second capacitors.
