Abstract: For obtaining a compact superconductive power switch for rapid switching speeds and with high dielectric strength, several winding layers (10a . . . 10h) with several windings each are lined up adjacent each other in axial direction. Between individual layers (10a . . . 10h), there are provided cooling/heating elements (8a to 8d) in order to transfer the high-current switch unit (1) to the superconducting state and the normally conducting state, respectively, by cooling/heating, i.e. for closing and opening said unit, respectively. Mutually adjacent current conductors have the switching current flowing therethrough in opposite directions, so that the high-current switch unit (1) is of low induction, which permits fast switching times in particular when the switch is opened by an additional current pulse.
