Abstract: A high voltage interrupter unit includes a switching chamber within which at least two electric contact elements of a contact system are arranged to be moved relative to one another. The contact system includes at least one mechanical element which is at least in part not in fixed mechanical connection with either of the two contact elements. In order to increase the mechanical endurance of the contact system, the at least one mechanical element is sheathed at least in part in a layer of a synthetic, abrasion resistant material.
