PROBLEM TO BE SOLVED: To reduce the number of components and relatively easily control the sizes, and to improve appearance. SOLUTION: Two neighbor operating knobs 14, 15 are united through a connecting portion 18 to form a single body. V-shaped separation varying part 18a and cylindrical parts 19, 19 having positioning guides 20, 20 are formed on the connecting portion 18, and pin-shaped positioning parts 22, 22 are provided on a switch bogy 11. When mounting the operating knobs 14, 15 on the switch body 11, front parts of the operating knobs 14, 15 are inserted into an opening 12 as well as fitting each of positioning guides 20 into the positioning parts 22. With cooperating effect of each positioning guide 20 and the positioning part 22, separating a dimension D2 between the operating knobs 14, 15 is narrowed not more than 0.5 mm for instance, and the separating dimension becomes to be maintained.
