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.

Abstract: A special-purpose light-guiding seat for pilot lamps of an electronic machine, which comprises a fixing base, a light-guiding device, and a light-pervious block, is basically mounted on an electronic machine housing for indicating the state of inside light sources (LED), in which the light-guiding device is substantially a transparent rod body having its front end connected with the light-pervious block while its tail end is extended to approach the light source; and the lightpervious block is jointed with the fixing base such that the outer-edge surface of the light-pervious block can be inserted and fixed flush on the machine housing for people to view from outside the lighting state of the light-pervious block easily and distinctly.
