Abstract
An input device and a handheld electronic device comprising the input device are provided. The input device comprises an elastic sheet and a switch sheet, both with alignment through-holes for precise alignment. Thereby, a protrusion of the elastic sheet is disposed precisely above a switch of the switch sheet. Because of the inerrable assembly of the input device, the handheld electronic device will have an acute response to the depression made by the user.

An input device, adapted to be assembled to an upper housing of a handheld electronic device, comprising:
- a switch sheet having at least one first alignment through-hole and at least one switch;
- an elastic sheet, disposed on the switch sheet, comprising:
- at least one protrusion oriented toward the at least one switch;.
- at least one cantilever connected to the at least one protrusion;
- a connecting portion, connected to the at least one cantilever and bonded to the switch sheet, the connecting portion having at least one second alignment through-hole, wherein the at least one first alignment through-hole and the at least one second alignment through-hole are overlapped with each other;
- and
- a cover disposed on the elastic sheet, wherein when being depressed, the cover abuts the elastic sheet to force the at least one protrusion to depress the at least one switch.
