Provided is a capacitance-sensitive touch switch. The main purpose of the present invention is to provide a touch switch of an electronic device, which is capable of sensing a constant variation in capacitance regardless of whether a cover panel of an entire surface is curved or flat, and which is capable of sensitively sensing a variation in capacitance even when the electronic device is used over a long time. To this end, the capacitance sensitive touch switch according to the present invention includes: a cover panel having a plurality of touch buttons arranged at a front surface thereof, and having at least one first coupling member arranged at each side of an edge thereof; an electrostatic panel provided on a rear surface of the cover panel, having lighting holes formed at a position being opposite to the touch buttons, and having electrostatic conductors formed integrally with the electrostatic panel in a direction perpendicular to the electrostatic panel at one side of the electrostatic panel adjacent to the lighting holes; a support panel having a second coupling member arranged at an edge corresponding to a position being opposite to the first coupling member arranged at the edge of the cover panel, having lighting holes formed at a position being opposite to the lighting holes of the electrostatic panel, and having through-holes formed adjacent to the lighting holes such that the electrostatic conductors pass through the through-holes; and a control board arranged at one side of the support panel, having a plurality of light emitting elements provided at a position being opposite to the lighting holes formed in the support panel, having at one side thereof adjacent to the light emitting elements through-holes for passage of the electrostatic conductors, and having at a rear surfaces of the light emitting elements one or more sensing means connected to respective ends of the electrostatic conductors passing through the through-holes. Thus, the present invention has the advantages of providing a touch switch of an electronic device, capable of stably sensing a constant variation of capacitance regardless of whether the cover panel of the entire surface is curved or flat, and capable of sensitively sensing a variation in capacitance even when the electronic device is used over a long time. |
