Abstract
A switch has a vacuum interrupter and a switch housing which holds the vacuum interrupter between two supply terminals. The vacuum interrupter contains a tubularly constructed, evacuated housing with a fixed contact member and movable contact member. A movable contact carrier of the movable contact member is guided out of the housing in a vacuum-tight manner by a bellows and is held on the housing axis by a slideway. The slideway has a bushing which is detachably mounted on a flange of the housing. The bushing has an axially aligned guide groove situated on an inner surface. A guide element held on the sliding body of the movable contact carrier is guided in this guide groove. The switch prevents undesired axial, radial and torsional acting forces from damaging the bellows, and therefore, ensures the vacuum-tightness of the vacuum interrupter is maintained during manufacturing assembly and operation.
