SOLUTION: When rotating a control shaft 22, a second rotary body 34 moderately rotates through a gear 32. When pushing the control shaft 22, since the control shaft 22 and the gear 32 are slidingly joined, both perform slide operation, a rubber member 42 is deformed through a drive body 33 by a movement of the control shaft 22, the rubber member 42 presses the arm part 41a, fixed contact points 38, 39 are turned on, and when a push is released in the next time, the arm part 41 returns to the former state by elasticity of the rubber member 42, the mutual fixed contact points 38, 39 are turned off, and control of a push switch is performed. When pulling the control shaft 22, the gear 32 meshes with the tooth part 28c of a first rotary body 28.
