Abstract: An improved, weather-sealed switch actuator arrangement especially suited for use in electrical or electronic apparatus that may be exposed to hostile ambient conditions. The switch actuator is fabricated of plastic, non-metallic materials wherein a base actuator member is overfitted with a pliant, weather-resistant material, which actuator may be snap-fitted into a recess in the housing of the associated apparatus. A plurality of hook-like tab members on the base actuator cooperate with a plurality of associated apertures in the bottom surface of the housing recess for captivation purposes. A peripheral ridge in the bottom surface of the recess makes a press fit into the material of the overfitted cover to provide a tight, weather-proof seal against water, sand and other dirt particulate. A center portion of the base actuator member is suspended in cantilever fashion with an operating tab or actuator extending laterally inwardly from the free end thereof.
