1. A full-area touch device comprising:
a supporting unit including a base plate, and a plurality of support resilient sheet sets connected to the base plate, the base plate having two first side edges that extend in a first axial direction, and two second side edges that extend in a second axial direction perpendicular to the first axial direction;
a touch control unit disposed on the support resilient sheet sets, and drivable to move the support resilient sheet sets relative to the base plate in a third axial direction perpendicular to the first axial direction and the second axial direction, the touch control unit being movable relative to the supporting unit between an unpressed original position and a pressed position; and
a plurality of limiting units disposed between the base plate and the support resilient sheet sets for limiting height position and travel distance of the touch control unit, each of the limiting units including a blocking portion that is disposed on the base plate, and a limiting portion that is disposed on a corresponding one of the support resilient sheet sets, the limiting portions of the limiting units extending in one of the first and second axial directions to be limited by the blocking portions of the limiting units.
