摘要: A circuit assembly for providing a switch sensor and capacitive sensor. The has first pattern of conductive material in plane second plane. An insulating member an intermediate separates the patterns. In area, openings to allow element contact responsive force being applied element. maintains spacing between also includes preventative capacitance configuration that limits non-intentional coupling area.
