Zusammenfassung: | A vacuum switch device has a housing body, a stationary electrical contact and a moving electrical contact, which is arranged within the housing body. With a movement of the moving contact towards the stationary contact, the contacts form an electrical contact. With a movement away the electrical contact is interrupted. A sliding bearing provides sliding support for the moving contact for its movement towards and away from the stationary contact. The sliding bearing has an electrically conductive material and at least partially electrically insulates the housing body. A spring element is supported on a spring support and presses the moving electrical contact in the direction of the stationary electrical contact. There is also provided a circuit with a main current path and a parallel auxiliary current path. The vacuum switch device is arranged in the auxiliary current path. |
