Abstract

Improvements in modular rotary switches for three-phase transformers, whose windings, primaries have in an end portion identical stages in the three windings, these switches comprising three groups of fixed plots arranged in a circle, connected to the sockets mentioned so that each group corresponds to a winding, three movable contacts electrically connected to each other capable of being rotationally driven and fit, in locked position, to support each other on a plot of a different group, support means and means for actuating the commutator, characterized in that the three mobile contacts are made in a single star piece with three branches forming a spring in a first contact-plot direction and in a second direction perpendicular to this first direction.
