摘要

Contact improvements for staggered switch selectors for transformers, which are suitable for fastening on vertically arranged insulating material elements, mainly on insulating rods of a drum cage of a selector, have a plane of horizontal symmetry and can interposed between two symmetrical contact bridges in the same plane, characterized in that the part that establishes the electrical contact consists of an annular flange with a very rounded cross section, preferably circular in shape.
