Patent ID: 8205997

Claim:
A touch control button apparatus, comprising: a circuit board; a touch control light emitting surface arranged above the circuit board with a distance; a touch sensing conductor disposed on the circuit board to produce a capacitance value variation if the touch control light emitting surface is touched by an object; a touch sensing device, for detecting the capacitance value variation of the touch sensing conductor; and a light emitting device disposed on the circuit board, under the touch control light emitting surface and surrounded by the touch sensing conductor; wherein the touch sensing device detects the capacitance value variation of the touch sensing conductor when the touch control light emitting surface is touched by the object, to determine if the light emitting device is lightened; and a sealing material filled in the space defined by the circuit board and the touch control light emitting surface and covering the circuit board, the light emitting device and the touch sensing conductor so as to form a flat touch control light emitting surface.
