Patent ID: 8859927

Claim:
A vacuum switch, comprising: a switching contact disposed in a vacuum chamber subject to a vacuum, said switching contact including: a stationary contact piece fixedly connected to said vacuum chamber and making electrical contact with a stationary contact connecting terminal; and a moving contact piece movably guided relative to said stationary contact piece between a disconnected position at a spacing distance from said stationary contact piece and a contact position in position in contact with said stationary contact piece; a drive unit for production of a drive movement; a switching mechanism connected to said drive unit and to said moving contact piece, said switching mechanism having an electrically conductive conductor section extending to said moving contact piece; and a connector device disposed to electrically connect a moving contact connecting terminal to said moving contact piece in the contact position, said connector device including a terminal contact with an insertion clamping contact piece, which is connected to said conductor section of said switching mechanism, and a mating clamping contact piece, which is fixedly connected to said vacuum chamber, and is electrically connected to the moving contact connecting terminal; said insertion clamping contact piece and said mating clamping contact piece being arranged with respect to one another to cause said insertion clamping contact piece to be electrically conductively clamped to said mating clamping contact piece as a consequence of the drive movement.
