摘要: A physical force capacitive touch sensor comprises a element on substrate, physically deformable electrically insulating spacer over the and conductive plane spacer. protective fascia may be placed provides an environmental seal for weather protection, but is not essential to operation of sensor. Back lighting accomplished with light transmissive layer having suspended metal target proximate plate. When are displaced toward plate capacitance value changes that change detected.
