ABSTRACT:
A starting switch assembly for an electric motor having a run winding, a starting winding, and a centrifugal actuator. The starting switch assembly includes a first enclosed switch electrically insertable between an electric motor starting winding and a power source to control the application of power to the starting winding. A second enclosed switch is also included, each of the first and second enclosed switches having its own housing for protecting the interior thereof from environmental particles such as lint. The first and second enclosed switches are mounted in a predetermined geometrical relationship and the assembly includes an actuating link responsive to an electric motor centrifugal actuator for simultaneously actuating the first and second switches. The first and second enclosed switches are mounted on a base by a relatively open frame which extends from the base to support the first and second exposed switches in the predetermined geometrical relationship.
