, 3C are opened and closed in three phases at once by levers 6A, 6B, 6C disposed on the operating shaft 4 which is reciprocally rotated by the drive source 10, in which two phases of the three-phase switches 3A, 3B, 3C are operated. Switches 3A, 3C
The three-phase switch 3 is parallel to and between the two-phase switches 3A, 3C and the other one-phase switch 3B.
The operating shaft 4 is arranged so that the distances from the two-phase switches 3A, 3C are the same, and the two levers 6A, 6C connected to the two-phase switches 3A, 3C are connected to the operating shaft 4. At the same time, the lever 6B connected to the other one-phase switch 3B is rotatably attached to the operating shaft 4 in a position symmetrical to the two levers 6A and 6C with respect to the axis of the operating shaft 4. A bevel gear 7A fixed to one lever 6A of the two levers 6A, 6C connected to the two-phase switches 3A, 3C and connected to the other one-phase switch 3B. A switch operating mechanism characterized in that a bevel gear 7B fixed to a lever 6B is configured to rotate in opposite directions by a bevel gear 12.
