ABSTRACT:
An improved brush assembly for use in an electrical device having a wall spaced from a current-carrying element. The brush assembly includes a holder having a first portion and an opposite second portion with a through channel opening at its opposite end through the holder portions. A terminal is mounted to the brush holder to have a turned end thereof received in the channel. Tangs are formed integrally with the terminal end for locking the terminal to the brush holder. The locking action is preselected to resist displacement of the terminal from the brush holder notwithstanding application of biasing spring force against the terminal by the spring provided for urging the brush into electrical contact with the current-carrying element of the device. Resultingly, the brush assembly may be preassembled and inserted to between the spaced wall and current-carrying element whereby the base portion of the terminal may be captured between the brush holder and the wall to further retain the terminal in position on the brush holder in the assembled electrical device.
