ABSTRACT:
Motor has outboard switch compartment with components therein such as a capacitor, thermal protector, terminal board, motor circuit controlling switch assembly, a manual switch, a thermal plastic molded cover for the compartment fastened with axially directed screws, and an optional rain shroud positively positioned on the end shield. The switch assembly is designed to have accurate contact alignment which will be maintained over the life of the switch; a wiping action of the contacts; a high amount of contact travel in terms of percentage of switch actuator travel; protected contact blade arms; and a multiple height mounting feature which assures a more optimum location of the switch at final assembly with respect to the location of the switch operating mechanism. Switch arms are essentially parallel and have contacts positioned directly in line with the actuating line of a switch actuator and an operating mechanism. A switch arm support is a molded synthetic material housing which, with a synthetic material molded switch actuator, provide precise and accurate preloading of the contact arms. Non-stick actuator features are included. Also included is a novel cover attaching approach and method, as well as switch assembly variable height mounting structure means and methods.
