Abstract

Cylindrical tap selector for step-down transformers in which fixed step contacts (2) are seated in at least one plane in the wall of an insulating material cylinder (1). A contact bridge (6) is provided for each plane, the inner end of which brushes against a contact ring (4) lying in the same plane which is arranged around a tubular operating shaft (3) made of insulating material guiding the contact bridge. The contact ring (4) is seated here on a ring (8) made of insulating material arranged around the operating shaft (3) and is locked to the latter by means of a plurality of dogs (9). The insulating material ring (8) is carried by at least three struts (10) made of insulating material which are supported on the wall of the insulating material cylinder (1). <IMAGE>
