<P>PROBLEM TO BE SOLVED: To provide an electrostatic touch switch device in which radiation noise is reduced. <P>SOLUTION: An electrostatic touch switch device 10 changes electrostatic capacity by performing a touch operation by an operator, thereby performing a switch operation, and includes: a first electrode on which the operator performs the touch operation; and a second electrode provided according to the first electrode. An AC voltage for performing touch detection is applied to the first electrode, and an AC voltage having the antiphase is applied to the second electrode, thereby providing the electrostatic touch switch device 10 in which radiation noise is reduced by cancelling a part of the radiation noise. <P>COPYRIGHT: (C)2012,JPO&INPIT |
