Abstract

A position sensor comprises a housing (10), a rotor (16) having brushes (36, 36) thereon rotatably mounted in the housing, a base plate (20) mounted to the housing, conductive members (48, 50, 52) on the base plate in electrical connection with the brushes, the base plate (20) forming a cover member for the housing so that an outer surface (47) thereof is exposed to the outside. Such an arrangement results in a position sensor with a reduced number of components having improved heat dissipation characteristics and better reliable electrical connections.
