LIGHT EMITTING TYPE CAPACITIVE TOUCH SENSOR

摘要

PURPOSE: A light emitting type capacitive touch sensor is provided to effectually obtain the various operations by additionally arranging dome unit and contact signal output terminals of elastic material. CONSTITUTION: A capacitance sensing pad(114) senses a capacitance change of an electronic device. The capacitance sensing pad has capacitance sensing patterns(112). The capacitance sensing patterns deliver the corresponding sensing signal to a PCB(Printed Circuit Board) side(150). The dome unit(201) is pressed by the printed circuit board according to the pressing operation of the capacitance sensing pad and an electric light emitting sheet(130). The contact signal output terminal contacts with the pressed dome unit. The contact signal output terminal delivers the contact signal by the printed circuit board.
