Touch switch and vehicle interior lighting device having the touch switch
Abstract:
A touch switch including: at least two of operation faces provided side by side; a detection electrode provided in each of the operation faces and including a wiring pattern of an electric conductor formed on or immediately below the operation face; and a controller connected to each of the detection electrodes to perform a switching operation by detecting variations of capacitance sensed by each of the detection electrodes, the variation of capacitance being generated when a human body part is in proximity to or in contact with each of the operation faces. At least one of the detection electrodes includes a wiring pattern more sparsely formed in a vicinity area of a boundary with another operation face adjacent thereto compared to a wiring pattern of the detection electrode provided in the adjacent operation face. Therefore, detection errors or accidental operations between adjacent switches can be prevented from happening.
