INPUT PANEL AND PORTABLE ELECTRONIC DEVICE USING THE SAME
First Claim
1. An input panel, applicable for a portable electronic device, the input panel comprising:
- a switch sheet, comprising;
a circuit board, having at least one contact pad; and
at least one dome switch, disposed on the contact pad;
a touch-sensing sheet, disposed on the switch sheet for sensing a touch action; and
an interposing sheet, disposed between the switch sheet and the touch-sensing sheet, wherein 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.

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.
