Abstract (en)

[origin: WO9934489A1] An electric switching device comprises a switch means (2) which presents an electrode gap (5) which is convertible between an insulating state and a conducting state, and members adapted to cause the electrode gap to assume conductivity. These members comprise a source for generally collimated radiation, and a system for directing the radiation towards the electrode gap in order to bring the gap or at least a part thereof to the form of a plasma. The radiation directing system comprises at least one directing element (15) for applying the radiation energy along a line (13) extending between the electrodes (3, 4). The directing element (15) is designed such that, and the generally collimated radiation inciding to the directing system is directed such that the radiation energy line (13) is at least partly laterally displaced in relation to the axis (20) of the inciding, generally collimated radiation.
