器自動機構５により操作される。2. Description of the Related Art Conventionally, an operation circuit of a high-voltage automatic switch is configured as shown in FIG. In the drawing, a closing magnet coil 1 drives a contact drive shaft (not shown) of a high-voltage automatic switch to perform a closing / cutting operation, and the current consumption of this coil 1 is generally as large as about 30 A.
Therefore, it is not possible to use a micro switch or a limit switch with a small rated current for opening and closing the operation current supplied to the coil 1 and use an electromagnetic contactor 2 with a large rated current. Further, the electromagnetic contactor 2 is opened and closed by a relay 4 operated by a micro switch or a limit switch 3 having a small rated current. The switch 3 is operated by the switch automatic mechanism 5.

確保されている。When the operating handle shaft 11 is rotated counterclockwise from this state, the cam 12 rotates and the follower 14 until the highest portion of the cam surface 13 having the radius R reaches the follower 14.
Is pressed by the cam surface 13 and retreats, and at the same time, the driver 17 also moves rightward while compressing the spring 19. With the movement of the driver 17, the knob 20 in the engaging portion 22 is tilted to the right. However, after the vertical position, the knob 20 is moved to the final position on the right end by the elastic force of the toggle mechanism in the toggle switch 6. Moves suddenly and stops. This state is shown in FIG. 3, and a gap c is provided between the knob 20 and the left end of the engaging portion 22.

When the operation handle shaft 11 is rotated clockwise, as the cam surface 13 having the radius R moves away from the follower 14, the follower 14 is pressed leftward by the spring 19 and moves forward following the cam surface 13. As the driver 17 advances, the engaging portion 22
The knob 20 inside is tilted to the left, but after passing the vertical position, the knob 20 rapidly moves to the final position at the left end, stops, and returns to the state of FIG.

The gap b,
c is formed. As a result, the toggle switch 6 can be turned on and off reliably and stably as if the human were reciprocating with a finger. As a result, the toggle switch 6, which could not be incorporated in the operating device because the stroke was short even if the rated current was large, can be used. The size of the container can be easily reduced.
