Abstract

A tap-changer selector for uninterrupted switching between two winding taps of a tapped transformer has fixed contacts arranged circularly in several horizontal planes at a selector housing and a centrally extending rotatable drive shaft in an interior of the selector housing and in each of the horizontal planes of the fixed contacts carries at least one movable contact for connection thereof. The selector housing consists of a plurality of honeycomb segments, and the honeycomb segments are arranged adjacent to one another in the circle in a horizontal plane. A plurality of honeycomb segments arranged in a plane in the circle are arranged vertically one above the other and the honeycomb segments have mounting regions and are so interconnectible by these mounting regions to form when at least two honeycomb segments are connected a mechanically positive connection between at least two mounting regions of the individual honeycomb segments.
