摘要

A switch device with brushes for use in a small electrical machine, more particularly a small battery-driven motor for use in record players, tape recorders and the like, said switch being formed by a thin plate of insulating material disposed perpendicularly to the axis of the machine and three thin, identical segments of electrically conductive material being applied thereto, preferably by a printing process, and biting the slots separating said segments, each brush comprising at least two independent parallel deflection elements, characterized in that The centers of the contacts between the commutator and the brush elements are arranged on different radii of the commutator, the angles between said radii being equal to each other.
