PROBLEM TO BE SOLVED: To prevent the malfunction of electric circuits. SOLUTION: A bent section 20D is formed toward a printed circuit board 17 of a main body section 20A at a leaf spring 20 of a mode lever 14 and a front end 20E of the bent section 20D is bent approximately perpendicularly. The front end 20E of the bent section 20D abuts on a grounding line 17A formed on the printed circuit board 17 by prescribed elastic force and is adapted to move in the state of abutting on the grounding line 17A at all times even when the leaf spring 20 rotates together with the mode lever 14. |
