Abstract (en)
[origin: EP0637829A1] A stage switching unit for use in transformers has a number of fixed contacts (Kn) mounted on a frame. Auxiliary contacts (5) are mounted on a slide element (3) that is subjected to the force applied by a spring (4) when a leadscrew (2) is rotated by a geared drive (1). The movable contact is mounted on a coupled mass (7) that is subjected to a separate spring force. The changeover between contacts occurs with a snap action.
