Touch keypad with chip

A capacitive touch keypad is a keypad uses the conductive touch of a human finger for input.
Unlike typical mechanical membrane switch, a completed cap-touch keypad is made by graphic overlay, sensor pad circuit(PCB or silver ink printed circuit), capacitive touch sensor chip, PCB circuit and related components.
