Abstract
An electrical switching device, especially a high-frequency switching device, comprising an elongate electrical switching element, a contact end of which is disposed between two opposite contact elements that are transversally spaced apart from each other. The switching element can be selectively moved perpendicularly to the longitudinal direction thereof towards one or the other opposite contact element by two adjusting elements that are located on both sides next to the switching element. In order to eliminate or at least reduce frictional processes and the risk of the electrical contact being damaged by abrasion, the switching element is made at least in part of magnetic material while the adjusting elements are formed by two magnet assemblies, the magnetic force of one magnet assembly or the other magnet assembly being selectively reducible or increasable.
