PROBLEM TO BE SOLVED: To provide a push-button switch capable of ensuring an excellent operation feeling while increasing a travel distance until operation force is maximized. SOLUTION: In this push-button switch, a dome-like reversing spring 3 is reversed by a pressing operation of a pressing member 5, and connection and disconnection of a contact part 2 comprising a moving contact 11 and a fixed contact 10 is carried out by the reversing operation; the pressing member 5 is provided, on its undersurface, with a projecting part 16 corresponding to a top part of the reversing spring 3; a rubber sheet 4 is arranged between the projecting part 16 and the reversing spring 3; and the rubber sheet 4 is held to allow the whole thereof including a peripheral part to be vertically moved with the pressing operation of the pressing member 5.
