A PLUG-IN BRUSH CARTRIDGE ABSTRACT OF THE DISCLOSURE A cartridge on which is mounted two active carbon brush assemblies plugs into a specially designed opening in one side of a motor housing of a power operated tool. As the cartridge is inserted or removed electric terminals mounted on the cartridge connect with or disconnect from terminals fixed on the motor housing to automatically establish or disconnect the electrical connections for controlling the motor operation. A single non-metallic screw holds the cartridge with both active brush assemblies in operative position within the opening with the active carbon brushes in juxtaposition and engageable with the commutator of the motor at diametrically opposed positions. The opening in the motor housing has an integral support therein. Such support also provides ramps to guide the carbon brushes up and onto diametrically opposite sides of the motor's commutator as the cartridge is plugged into the opening. The cartridge has recesses to removably mount a spare non-metallic screw and a pair of spare carbon brushes in a manner to prevent damage due to operating vibration and casual droppage of the tool. The shape of the outer surface of the cartridge is designed to conform to the shape of the outside of the motor housing.
