Abstract
A brush-holder for rotating electrical machines includes a brush and a compression spring disposed in a shaped metallic sleeve encased in an insulating support adapted to be mounted on the frame of the engine. The insulating support includes at least one projecting stop which cooperates with a notch provided on the sleeve, so that the sleeve is precisely located at a predetermined longitudinal position within a sheath on the support. In addition to positioning the sleeve, the stop also serves to limit travel of the spring as the brush wears down.
