Title:
静電容量式センサ
Document Type and Number:
Japanese Patent JPWO2002073148
Kind Code:
A1
Abstract:
A capacitance element electrode (E 1) and a reference electrode (E31) are formed on a substrate (20) so as to be opposite to a displacement electrode (40). A dome-shaped movable switch electrode (E21) is disposed so as to be in contact with the reference electrode (E31) and at a distance from a fixed switch electrode (E 11) formed inside the reference electrode (E31), and to cover the fixed switch electrode (E11). When an operation is applied to a detective member (30) and a portion of the movable switch electrode (E21) in the vicinity of its top is displaced to be brought into contact with fixed switch electrode (E11), a switch is turned ON. On the other hand, from a change in capacitance value of a capacitance element (C1) formed between the displacement electrode (40) and the capacitance element electrode (E1), the intensity of the force to the detective member (30) can be recognized.
