PROBLEM TO BE SOLVED: To solve the problem of becoming contrary to cost reduction and miniaturization of a control part by an increase in the substrate area, due to increasing even a circuit constitution, when switch electrodes arranged in a panel switch become a large number, by increasing the detecting signal line number used for signal input to a switch switching circuit by that number. SOLUTION: A capacitance type touch switch is composed of a switch electrode part of arranging a plurality of switch electrodes divided in a plurality into films as an input operation part, an arithmetic processing unit for detecting a capacitance change in the switch electrode part, and a control part provided with a capacity change measuring part incorporated with a control program required for operating the arithmetic processing unit and incorporated with a circuit for transmitting a capacity change in switches to the arithmetic processing unit, and determines input of the switches by a change in capacitance. The respective switches divided into a plurality are connected to a grouped detecting signal line of the same number as the switch electrodes divided into a plurality via a wiring part, and a combination of the connection is formed as a single switch.
