Abstract
A touch switch device with an illuminator for detecting a close approach or contact of a human body to an operation surface includes: a wiring board having a light-emitting device and a detection electrode on a one surface side; a light guide plate located on the one surface side of the wiring board to emit light from the light-emitting device to the outside from the operation surface opposite the wiring board; and a detector connected with the detection electrode to detect change in electrostatic capacity to be generated at the detection electrode when a human body closely approaches or contacts the operation surface to produce a detection signal corresponding to the detected condition. An operation part is displayable on a surface of the light guide plate to serve as the operation surface, and the operation part is positioned corresponding to a position of the detection electrode.
