ABSTRACT:
A brush holder assembly for electrically-coupling relatively movable conductors comprises a brush holder having a cavity which slidably receives a brush and having a pair of shoulders located on opposite sides of the cavity to confront a conductor. An electrically-conductive twin coil spring is mounted in the cavity with its saddle portion engaging one end of the brush and its coils disposed adjacent the shoulders for biasing the other end of the brush into contact with the conductor. An electrical contact member is interposed between at least one of the shoulders and its engaged spring coil to provide a current path into the side of the brush adjacent the coil for improving the overall performance of the brush assembly.
