ABSTRACT:
An input panel for a portable electronic device including a switch sheet, a touch-sensing sheet and an interposing sheet is provided. The switch sheet includes a circuit board and at least one dome switch. The circuit board has at least one contact pad, and the dome switch is disposed on the contact pad. The touch-sensing sheet is disposed on the switch sheet for sensing a touch action. The interposing sheet is disposed between the switch sheet and the touch-sensing sheet. The touch-sensing sheet contacts the dome switch when the touch-sensing sheet is pressed, so that the dome switch is deformed elastically to switch on the contact pad.
