Abstract:
1. A vacuum switch having a moving switching unit which is arranged within a vacuum interrupter chamber and comprises a contact plunger, an insulator and a drive or switching rod which move with one another, which drive or switching rod is introduced into the vacuum interrupter chamber through a bellows composed of metal, and having a stationary contact which is inserted into the housing of the vacuum interrupter chamber, with a first end of the insulator being firmly connected to the contact plunger and with a second end of the insulator being firmly connected to the drive or switching rod, and with the contact plunger having a flexible electrically conductive connection to a conductor which makes an electrically conductive connection to at least one outgoer contact which is arranged at the side, wherein the internal cross-sectional area of the vacuum interrupter chamber at the level of the at least one outgoer contact around the contact plunger is covered over an area by electrically conductive covering elements which are arranged thereon, are in the form of films or platelets, are arranged one above the other in layers and are each at least partially coincident.
