Abstract (en)

A selector switch for switching taps of a transformer comprises a switching shaft insert (11) including two switch contacts (12) and a network terminal contact (13). Fixed step contacts (14) are circumferentially arranged on a cylinder (22) provided around the switching shaft insert, the fixed step contacts being connected to taps of the transformer. A respective vacuum switch (15) is connected between each of the switch contacts and the network terminal contact, a cam structure (23) is circumferentially arranged on the inner surface of the cylinder, and the switching shaft insert comprises further, for each of the vacuum switches, a radially movable lever (24) provided in its outer end with a cam follower (25) arranged to follow the cam structure. Each pair of the levers and vacuum switches comprises structural elements (26, 27) in mutual engagement with one another which force the vacuum switch to be actuated axially by means of the lever being moved radially.
