Abstract
A switch device may include a non-conductive operating portion provided with a plurality of operating areas inside an outer edge part of the operating portion, an electrode sheet spaced from the operating portion and having a plurality of electrodes each including at least one detection electrode and being arranged to face a respective operating area, and a detecting unit that may detect operations of the plurality of operating areas. An inner part of the operating portion positioned inward of the outer edge part may be displaceable in a facing direction of the operating areas and the electrodes. The detecting unit may be configured to determine an operated operating area, which may be operable by touch or push operation, based upon a position of at least one of the detection electrodes, a change in capacitance of the detection electrode, and a changing amount in capacitance of the detection electrode.
