  • Vacuum interrupter and switch pole
    Patent number: 9230760
    Abstract: A vacuum interrupter has a housing with at least a first metal flange through which a first connection pin extends into the vacuum interrupter in a vacuum-tight manner to a first contact. The housing has at least one insulating-material housing region formed by a disc-like insulator. A second connection pin extends into the vacuum interrupter in a vacuum-tight manner to a second contact. The vacuum interrupter can be produced in a cost-effective manner with a compact construction. There is also described a switch pole for a switching device having a vacuum interrupter.
