Summary:PROBLEM TO BE SOLVED: To provide a two-stage switch in which reduction of the number of parts is achieved, which can be manufactured inexpensively with a simple constitution, and in which a first-stage switch can be input-operated by a smooth touch while a second-stage switch can be input-operated surely by experiencing a feeling of click. SOLUTION: In the peripheral part of the rear face of an operation part 24, a leg-shaped peripheral wall 25 is formed which forms a gap between a pressing part 23 and a dome member 13 by extending out in a direction orthogonal to a switch circuit board 1 at the time of non operation, and bent by a second switch operation. At the tip side of the leg-shaped peripheral wall 25, a flange part 26 is formed which is arranged and installed parallel by forming a slight gap between the switch circuit board 1 at the time of non operation, and at the flange part 26, a key top side first contact 22 is formed opposing to a board side first contact 11 formed at the switch circuit board 1.
