Thus, the switch knob 50 is pushed in the direction of the printed circuit board 10.

On the other hand, in order for the outer rotary member 46 and the upper body 80 to be pushed in the direction of the printed circuit board 10 in a secondary manner, the second breakage is caused by the outer signal conductor 44 which contacts and supports the lower side of the outer rotary member 46. It is preferable that the rib 130 is formed, and the second fracture portion 140 is formed at the junction of the upper body 80 and the outer body 42.
