Abstract
A control device comprising an electrical switch having an actuator disposed for reciprocal movement in a housing and provided with a substantially planar surface whereon a pawl is mounted for rotation in a plane adjacent the planar surface. The pawl includes a plurality of cam surface portions disposed for engagement with projections within the housing to convert reciprocal movement of the actuator into controlled rotary movement of the pawl in a uniform direction and thereby determine the sequence of operating conditions produced by the actuator. At least one pair of resilient arms extend from respective opposing portions of the pawl and into resilient pressure engagement with the substantially planar surface for exerting respective balanced tensile forces on the opposing portions of the pawl and enabling the pawl to resist free rotary movements and permit controlled rotary movements thereof.
