ABSTRACT:
A touch pad pushbutton structure includes two pushbuttons mounted to a casing of an electronic device, such as a notebook computer. Each pushbutton has a circumferential flange. Two deflectable U-shaped ribs integrally extend from the flanges of the pushbuttons and connect between the pushbuttons at opposite ends of the pushbuttons. The ribs are fixed to the casing for movably supporting the pushbutton on the casing whereby each pushbutton is allowed to move from a released position where the flange of the pushbutton engages the casing to an actuated position where the pushbutton is depressed and the flange thereof separated from the casing for activating a circuit to generate a signal indicating the depression of the pushbutton.
