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. The center portion when depressed by the thumb of a user, for example, causes the actuator to extend through and engage the toggle knob of a microswitch device, for example, positioned internally of the apparatus housing.
