Summary:PROBLEM TO BE SOLVED: To provide a movable contact for a switch capable of preventing a pressing protrusion from dislocating out of an inverse spring in which the pressing protrusion is bonded to and fixed on the inverse spring, to provide a sheet with a movable contact, and to provide a switch device. SOLUTION: The movable contact for the switch has the inverse spring 14 which is reversed by pressing, and the pressing protrusion 15 bonded to and fixed on the outer surface of the inverse spring 14. Bending stress generated on a gluing layer 28 intervened between the pressing protrusion 15 and the part to be bonded is reduced by restraining deflection of the part to be bonded since an annular protrusion 23, which projects in ring shape from the outer surface of the inverse spring 14 to the outside at the part to be bonded and raises bending rigidity of the part to be bonded where the pressing protrusion 15 is bonded, is arranged on the inverse spring 14, and it is prevented that the pressing protrusion 15 is dislocated from the inverse spring 14.
