Abstract
A pushbutton switch having an extremely small size for its number of contacts and capability. The switch has a tubular insulating housing with the snap-in pushbutton non-rotatably keyed in and extending through the upper reduced bushing end thereof for longitudinal reciprocal movement. Bifurcated spring contacts are molded into a snap-in base and extend upwardly therefrom into the housing. A ring-shaped common terminal is snap-in attached to the base before snap-in assembly thereof in the housing. A cylindrical bar movable contact guided in grooves in the housing is snap-in assembled between tabs in the bifurcated inner end of the snap-in pushbutton and keeps the snap-in tabs spread apart to prevent removal of the pushbutton from the housing. A helical return spring lines the walls of the housing and is compressed between the common terminal and the ends of the movable contact bar to act as both a return spring and as a connector. A tactile tongue integral with the pushbutton acts on the housing to provide operating position 'feel' to enable the user to sense when the contacts close.
