Abstract
the arrangement has at least one anode (10) and a cathode (11) which are arranged at a constant distance apart to form an intermediate vol. A cathode vol. (12) bounding on the cathode has at least one trigger opening (19) for igniting a plasma. The cathode has several electrode openings (14) which connect the cathode vol. to the intermediate vol. so that discharge channels are formed when the plasma is ignited. The geometric shape and size of the cathode, anode, electrical leads and electrode openings is selected so that a current flowing through the plasma forms at least two current loops (S1,S2) which exert opposite forces upon the plasma which at least approximately compensate each other at several points in the intermediate vol. USE - for switching strong electrical currents ADVANTAGE - enables minimal wear switching of strong currents even with long current pulse lengths.
