Abstract
The vacuum switch is compact, requires little effort, and provides a reliable current path having a high current-carrying capacity between the terminals of the vacuum switch, particularly at high switch-on speeds. The vacuum switch has a vacuum chamber, in which a vacuum is present and in which a switching contact is arranged. The switching contact includes a fixed contact piece firmly connected to the vacuum chamber and in electrical contact with a fixed contact terminal, and a moving contact piece movably guided relative to the fixed contact piece. The moving contact piece is at a distance to the fixed contact piece in a disconnect position and contacts the latter in a contact position. A drive unit produces a drive movement. A switching mechanism is connected to the drive unit and the moving contact piece and includes a conductor section that is electrically conducting up to the moving contact piece. A connector connects a moving contact terminal electrically to the moving contact piece in the contact position. The connector has a clamping contact, which has an insertion clamping contact piece connected to the conductor section of the switching mechanism and a mating clamping contact piece firmly connected to the vacuum chamber and electrically connected to the moving contact terminal. The insertion clamping contact piece and the mating clamping contact piece are arranged relative to each other such that the insertion clamping contact piece is clamped with the mating clamping contact piece in an electrically conducting manner as a result of the drive movement.
