Abstract

Two adjacent operation knobs (14, 15) are formed integrally with each other via a coupling portion (18) On the coupling portion (18), there are formed a V-shaped gap variable portion (18a) and cylindrical portions (19) having positioning guide portions (20). There are provided pin-shaped positioning portions (22) on the switch body (11). To assemble the operation knobs (14, 15) to the switch body (11), each of the positioning guide portions (20) is mated with the positioning portions (22) and the front portion of the operation knobs (14, 15) is inserted into the opening (12). In cooperation with each of the positioning guide portions (20) and the positioning portions (22), the spacing dimension D2 between the operation knobs (14, 15) is narrowed, for example, down to 0.5 mm or less, and the spacing dimension is to be sustained.
