PROBLEM TO BE SOLVED: To provide a switch which realizes no-contact, small size, and low cost by using a microcomputer that recognizes the switching operation in order to obtain as a DC electric signal the switching operation signal of a push button switch by the detecting part in which the electrical resistance changes when the shape is changed. SOLUTION: The switch device is constructed of a push button switch part which uses a flexible resistance change detection material in which carbon particles are dispersed in silicon rubber, and in which a detecting part, a terminal part, and an operating part are integrated, and a microcomputer which has memorized data of switching recognition line for comparing the resistance drop characteristics at the time of closing and opening.
