Abstract: A high voltage switching device is operated by a compressed gas valve having an electrodynamic operating means. The operating means comprises a stationary coil which is inductively connected to a short-circuit winding supported by the movable member of said valve. To operate the switching device a capacitor located at high potential is connected to said coil through a photoelectric switching member.
