Abstract
The invention provides a brush cartridge for a commutator-type motor. The brush cartridge includes a housing that is made of an electrically conductive material and that has an integrally formed terminal so that the cartridge can be plugged into a circuit without the need for wiring. The brush cartridge also includes a brush supported in the housing for sliding movement relative thereto and a spring member for biasing the brush into engagement with a commutator on the motor when the cartridge is installed. The brush cartridge also includes a flexible shunt connected between the housing and the brush. The shunt limits the range of sliding movement of the brush to permanently retain the brush in the housing.
