发明名称 PRESSURE DEPENDENT CAPACITIVE SENSING CIRCUIT SWITCH CONSTRUCTION
摘要 A user interface which includes a capacitive measurement circuit with a sense plate covered by an electrically conductive cover member, and wherein said circuit may sense two types of events, said types distinguished by an inverse change in measured capacitance, and wherein user proximity and touches with less than a minimum required force constitute one event type, and touches with more than said minimum force constitute the other event type.
