ABSTRACT:
A switch chamber for a vacuum switch including a housing having at least one insulating tube with an end face and an axial axis. A contact pin having an exterior surface is arranged for supporting the switch chamber. A stationary contact is held by the contact pin within the housing and has a frontal face. A movable contact contacts the frontal face of the stationary contact in the on-position of the vacuum switch under the force of a contact spring. A seal including a bellows connects the movable contact with the housing in a vacuum-tight manner. A terminating cover is connected to the insulating tube and to the contact pin in a vacuum-tight manner and transfers to the housing impact forces generated when the vacuum switch is switched on. The insulating tube comprises a ceramic tube. The terminating cover has a corrugated shape including at least one full corrugation and has an outer cut edge fastened to the end face of the ceramic tube and an inner cut edge fastened to the exterior surface of the contact pin.
