ツチ。 An upper electrode and a lower electrode that face each other with a spacer interposed therebetween; a click spring that is formed in a circular shape from the outer edge through a rising portion and is disposed above the upper electrode; and a click spring that is disposed further above the click spring. The switch device is provided with a pressing sheet in which the upper electrode and the lower electrode come into contact with each other with the reversal action of the click spring, and a substantially disc-shaped protection member is provided between the click spring and the pressing sheet. , the protective member includes an annular actuating part that comes into contact with the upper surface of the click spring between the central part and the rising part of the click spring and presses down the click spring when pressed; and an outer periphery of the annular actuating part. What is claimed is: 1. A membrane switch characterized in that a membrane switch is provided with an annular protection part formed in a concave shape with respect to the click spring so as not to contact the rising part of the click spring and cause damage when the click spring is pressed.
