Touch input device with button function

A touch input device with a button function, said touch input device comprising:

• a base member comprising plural perforations, wherein said plural perforations are located at a bottom side of said base member;
• a touch module disposed over said base member and covering said base member, wherein when said touch module is touched and a touched position is detected by said touch module, said touch module generates a touch signal;
• a triggering switch disposed on said touch module, wherein when said touch module is depressed, said triggering switch is triggered to generate a button signal corresponding to said touched position;
• a coupling module disposed on a lower part of said touch module, wherein when said touch module is depressed, said coupling module is swung relative to said touch module to trigger said triggering switch;
• and
• plural movable pads disposed on the coupling module, and penetrated through said corresponding perforations of said base member to be exposed outside said base member, wherein when said touch module is depressed, said plural movable pads are moved relative to said corresponding perforations to push said coupling module, so that said coupling module is correspondingly swung.
