<P>PROBLEM TO BE SOLVED: To provide a tactile switch having waterproofness. <P>SOLUTION: The tactile switch 10 comprises a circuit substrate 1 provided with a pair of fixed electrodes 2, 3 separated from each other; an elastic cover sheet 5 having a conductive thin film 6 provided so as to oppose to the fixed electrodes 2, 3; and a sheet-shaped spacer sheet 4 interposed between the circuit substrate 1 and the cover sheet 5 in an adhesion state so as to surround the conductive thin film 6, and supporting the cover sheet 5 so as to separate the pair of the fixed electrodes 2, 3 and the conductive thin film 6. When the cover sheet 5 is pressed, the conductive thin film 6 is pressed against the pair of the fixed electrodes 2, 3 to conduct, thereby bringing the pair of the fixed electrode 2, 3 into conduction with each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
