    摘要: A one piece seal for an electric switch for sealing the spaces between a pivotal switch actuator and its supporting frame and between such frame and the switch base. This seal comprises a generally rectangular molded member of resilient material having a raised central boot portion containing a pair of downwardly extending leg openings for sealingly receiving respective legs of the switch actuator, a pair of lugs or pads on its bottom surface for locating and retaining the seal with respect to the switch base, and a crisscross pattern of shallow raised ribs on at least one surface of the seal along the perimeter thereof. The seal is pinched between the frame and base, compressing the ribs, and hugs the actuator legs to provide an economical but effective seal.

    摘要: A protector assembly and method for protecting motor windings from an overload condition. The assembly comprises a thermally responsive protector, a skirt, and a sleeve. The protector comprises a housing, an end cap, at least one terminal, and a thermally responsive member. The end cap covers an open end of the housing. The terminal extends through the end cap. The thermally responsive member is within the housing and adapted to be electrically coupled to the motor winding via the terminal. The protector is adapted to be positioned in heat-transfer relation wit the motor winding in a manner such that the thermally responsive member is responsive to an overload condition of the motor winding. The skirt and sleeve are of dielectric materials. The skirt is positioned on the protector in a manner such that the skirt surrounds the end cap and the terminal. The skirt is between the end cap and the sleeve. The skirt and sleeve are adapted to provide a dielectric barrier between the protector and the motor winding when the protector is positioned in heat-transfer relation with the motor winding.
