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.
