PROBLEM TO BE SOLVED: To speedily and reliably mount micro switches with one screw in a condition where they are laminated in plural layers, by forming a projecting part on one outer surface of the switch provided with a through hole to be inserted with a mounting screw and providing a recessed part on another outer surface, in order to fitting them each other. SOLUTION: In a first micro switch 4, a projecting part 4h is formed on a mounting surface 4e of a hole 4g to be inserted with a screw 4e. The projecting part 4h is fitted in a fitting hole 2b of a bracket 2, in order to position a first micro switch 4 on the bracket 2. A recessed part 4i is formed on the rear surface of the first micro switch 4 so as to be positioned on an axial line of the projecting part 4h. A projecting part 5h and a recessed part 5i are formed in a second micro switch 5. The projecting part 4h is fitted in the fitting hole 2b, and the projecting part 5h is fitted in a recessed part 4i. The screw 6 is inserted into the through hole 5g of a second micro switch from an opening on its rear surface, in order to laminate the first and second micro switches 4, 5.
