摘要： A moving contact of diaphragm-like resilient metal capable of a vertical self-restoring deformation is disclosed. The moving contact has a frame structure of upwardly-inflected generally partially cylindrical configuration in constant contact with one of several fixed contacts, and a central structure of generally partial hemispherical configuration, convexed in the same direction as the inflection of said frame structure, integrally formed with said frame structure but separated therefrom by at least one elongated and curved slot partially surrounding said central structure, so as to be deformable at least partly independent from the deformation of said frame structure. Said moving contact, when it receives a pushing-down action on its central structure, first deforms resiliently at its frame structure and then at its central structure sequentially, so that it is designed to be brought into contact with corresponding fixed contacts in consecutive order. Thus the present invention can provide a smaller, lighter and less expensive, push-on type switch capable of performing a two-stage switching operation in a single pushing-down manipulation of its actuation member with a notched touch in the same direction.
