ABSTRACT:
The brush holder comprises an electrically insulating body having a pair of apertures through which extend first and second brushes, which are movable by means of a single resilient member acting simultaneously on both brushes. This solution enables the wear on the brushes to be reduced significantly, particularly on the negative brush which normally tends to be worn away more rapidly.
