Abstract
Brush card or holder assemblies are disclosed. The assemblies avoid any need for a separate plastic cap and utilize a lead wire (which could be or include a rod or other electrically-conductive device) both electrically to connect a brush to an external component and mechanically to fix the position of one end of a mechanism, such as a spring, for biasing the brush toward the surface of a commutator or other rotating machine element.
