<p><P>PROBLEM TO BE SOLVED: To prevent impedance from being changed due to the formation of a new conductive passage, in a surface-mounted contact. <P>SOLUTION: A series of insulation coating films Fa are formed on an inner face of a base plate 3, that is an inner face of a spring 6, that is an inner face of a movable plate 8, and that is an inner face of a guide 4. Furthermore, the other insulation coating film Fb is formed on a top face of the movable plate 8. As for a region where the insulation coating films Fa are formed, no new conductive channels are formed even if a movable part 7 comes in contact with the other part when elastically deformed in a direction approaching a base 2. Therefore, such a problem that an electric resistance value as a whole, that is impedance, is delicately changed at forming such electric conductive channels is not generated, and also, failures caused by an impedance change do not occur. Since a magnetic body of the insulation coating film Fb is dispersed, the magnetic body is functioned as a noise filter. The insulation coating film Fb fitted on an adsorption face 9 enhances the detection accuracy of the adsorption face 9 by an optical means. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
