A tap switch of a tapped transformer comprises a contact bridge, which is rollable along two circular arcs and which includes two contact rollers (8, 9) axially connected with each other and rotatably mounted in a contact bridge carrier. The contact arrangement also comprises stationary contacts, which are arranged on the circular arcs and which are constructed as individual contacts (2, 3) on one arc and as a contact track (6) on the other arc. A connection between two contacts of the two arcs is effected by means of the rollable contact bridge. The axial connection of the contact rollers (8, 9) is by way of a flexible conductor (12). Each roller (8, 9) is rotatably mounted on a respective arm (10, 11) of the contact bridge carrier and the arms (10, 11) are movable relative to each other. <IMAGE> |
