ABSTRACT:
A pedestrian push button that discourages vandals and resists weather-related damage. The plunger is contained in a sleek, solid housing formed by a cup-shaped front cover that overlaps and substantially encloses a shallower, cup-shaped body, to protect the electrical components inside. The body is attachable from the inside to the traffic pole or other support surface, and the cover engages the body by means of a “twist-lock” connection that is hidden from view in the installed device. This reduces the appeal of the push button to vandals while at the same time making it easier for authorized personnel to open the housing for service and repair. The back of the body is contoured to conform to both flat and curved support surfaces, making the push button easy to mount securely regardless of the shape of the support surface.
