Abstract
The vacuum switch is duly provided with a gas-tight, evacuated envelope housing fixed and movable contacts. At least one contact carries a disc-shaped contact part with a sleeve connected to it or made in one piece with it. A conductor is provided in the sleeve, connected in series with the disc-shaped contact part. The conductor (13, 14) in the sleeve (11, 12) is spiral shaped and generates a magnetic field helping to break the switch current. Typically, the housing has a cylindrical insulated portion (1) with two metallic discs (2, 3) closing the ends. The rod shaped terminal conductor (4) projects through one disc (2). This conductor (4) leads a fixed contact (6).
