KEYPAD AND/OR TOUCHPAD CONSTRUCTION

摘要

A capacitive keypad and/or touchpad construction includes a flexible or rigid printed circuit board and a non-conductive keypad/touchpad top surface layer. A semi-conductive adhesive layer in between said flexible or rigid printed circuit board and said non-conductive keypad/touchpad top surface layer serves both to connect the top surface layer to the printed circuit board and to act as capacitive sensing layer.
