1. A full-area touch device, comprising:
a bottom plate including a bottom plate periphery;
a touch unit disposed above said bottom plate along an axis, and including a touch pad, a circuit board that is connected to a bottom side of said touch pad, and a pushbutton switch that is disposed on a bottom side of said circuit board;
a resilient unit in a shape of a plate, disposed between said bottom plate and said circuit board, and including a positioning region that is connected to said bottom plate, a peripheral edge that surrounds a periphery of said positioning region, a connecting frame subunit that is disposed between said positioning region and said peripheral edge, and a slot region that is located between said positioning region and said peripheral edge, said slot region having a contour that is greater than a contour of said bottom plate periphery, said slot region surrounding said positioning region, said connecting frame subunit being in a shape of a surrounding frame and being positioned with respect to said circuit board, wherein, when said touch unit is pressed toward said bottom plate, said connecting frame subunit being pushed by said touch unit such that said resilient unit is resiliently deformed and that said connecting frame subunit is bent relative to said positioning region; and
a supporting unit in a shape of a surrounding frame, connected to said resilient unit and positioned with respect to said circuit board, and including a fixing frame subunit that is connected to said connecting frame subunit, and a plurality of supporting members that are connected to said fixing frame subunit, each of said supporting members extending across said slot region.
