1. A full-area touch device comprising:
a supporting unit including
a base plate that has a lower end surface and an upper end surface opposite to said lower end surface, and
a plurality of resilient sheet sets that are connected to said base plate;
an adjusting unit mounted to said supporting unit and including
a limiting member, and
an adjusting member that is disposed under and abutting against said limiting member such that a top end of said limiting member is disposed above said base plate, and that is movable to adjust a distance between said top end of said limiting member and said upper end surface of said base plate; and
a touch control unit mounted to said resilient sheet sets, including a tact switch that is disposed above and aligned with said limiting member, and being downwardly movable relative to said supporting unit against a resilient force of said resilient sheet sets from an initial position to a pressed position for contacting said limiting member;
wherein said base plate further has a through hole that extends through said lower end surface and said upper end surface;
wherein said supporting unit further includes a bottom plate, said base plate being stacked on said bottom plate, said bottom plate having a top surface that faces said lower end surface of said base plate;
wherein said adjusting unit further includes a nut member mounted on said bottom plate;
wherein said adjusting member extends through said through hole, and has
a bottom end portion that is threadedly secured to said nut member and that is formed with an operation recess, and
a top end portion that is opposite to said bottom end portion and that abuts against said limiting member; and
wherein said limiting member has
a circular limiting plate that is disposed between said tact switch and said adjusting member, said adjusting member abutting against said circular limiting plate, and
a pair of connecting plates that interconnect said circular limiting plate and said base plate, and that are deformable to produce movement of said circular limiting plate relative to said base plate.
