PURPOSE:To improve reliability by providing an elastically supporting part mounted on a circuit substrate while protruding from an elastic cylindrical part, a plurality of elastic leg parts on the cylindrical part, an elastic switch having a movable contact formed in positions opposing to respective fixed contacts on the cylindrical part. CONSTITUTION:A rubber switch 12 is composed of a cylindrical part 14, rectilinear-shaped elastic leg parts 15, and a rectangular elastically supporting part 13, and is constructed in such a way that the first and the second movable contacts 16, 17 are formed at the lower end of the elastic leg part 15 and at the lower part of the cylindrical part 14. Thus, respective individual switches 12a, 12a are continuously formed at one time by an extrusion forming method, and it frees the dies from being complicated, so that there is essentially no dimensional scatter in products. Consequently, highly reliable switch devices can be obtained at a small cost. |
