Abstract
A keypad is comprised of a supporting frame, a plurality of snap action domes, and a plurality of pushbuttons each overlying a dome, all of the above being integrated and formed of a single piece of elastomeric material, the pushbuttons each being surrounded by a thin piece of the material buttressing the pushbutton upwardly, each of the thin pieces of material and an associated portion of the pushbutton forming a dome. The thin pieces of material extend from and are continuous with the frame. Each conducting button is disposed below a corresponding dome and is located such that when a pushbutton is pushed downwardly, its associated dome collapses, moving an associated button downwardly.
