The present invention is an improved brush card consisting of a non conductive card having a commutator aperture, and a pair of tongue and groove connectors. Each tongue and groove connector consists of at least one pair of parallel channels formed on the card adjacent the aperture and extending along the card perpendicular to the commutator aperture, the card forming a pair of parallel opposing channel edges adjacent the parallel channels. A portion of the card forms an elongated tongue separating the pair of channels, the tongue having a distal end extending towards the commutator aperture and a proximal end opposite the distal end. The brush card also includes at least one conductive brush slidingly mounted to each tongue, the brush having opposite first and second sides, the brush having a central groove dimensioned to receive the tongue. Each brush also has a first groove extending along the first side of the brush, the first groove dimensioned to receive one of the channel edges. Each brush also has a second groove extending along the second side of the brush, the second groove dimensioned to receive the other channel edge. The card further includes a biasing spring mounted to each tongue and positioned between the brush and the proximal end of the tongue, the biasing spring biasing the brush towards the commutator aperture.
