Abstract:
1. A capacitive switch of an electric/electronic device, comprising: a plurality of contacts which are disposed at a front of a control panel; a plurality of capacitive sensors which are disposed at a rear of the control panel, respectively face the contacts, and detect capacitance variations caused by static electricity transmitted through the contacts; and a plurality of void removal elements which are respectively disposed between the capacitive sensors and the contacts, to remove a plurality of voids between the capacitive sensors and the contacts and electrically connect the capacitive sensors and the contacts, and are formed of a conductive elastic material, wherein part of the control panel has a flat curved surface, at least two contacts are disposed on the flat curved surface of the control panel so that various sized voids are formed, and the degree to which the void removal elements are elastically compressed between the capacitive sensors and the contacts varies according to the sizes of the plurality of voids.
