  • Patent number: 8263892
    Abstract: A high-voltage switch contains two contact members, which can be moved relative to one another along an axis, a nozzle for blowing out a switching arc with quenching gas, and a stationary direction-changing transmission, which is connected to the nozzle and to the second contact member. The nozzle has a hollow insulating body, and a metallic annular body which is arranged at a blowing-out end of the nozzle, is connected in a formfitting manner to the insulating body, and supports an input or output drive element of the direction-changing transmission. This switch can be manufactured easily and at low cost, and provides good mechanical and electrical characteristics. The annular body has a concentrically arranged intermediate ring, which causes the form fit with the insulating body, and a ring, which is pushed onto the intermediate ring and is attached to the intermediate ring, for supporting the input-drive or output-drive element.
