As a conventional switch, for example, there is one that opens and closes a power distribution line by moving a movable electrode up and down by operating a mechanism part. In this switch,
One movable electrode has a weight of 3 to 4 kg,
Therefore, when opening the three phase movable electrodes of R, S, and T at the same time, it is necessary to lift the three movable electrodes, which weigh approximately 10 kg. Therefore, in order to prevent the movable electrode from wobbling laterally when going up and down, a total of three pillars are arranged, two on the front side and one on the back side.

６を介して支柱５にかからなくなる。 Fixed to the fixed plate 14 fixed to the movable electrode 4 is a handle 13 that is used when removing the movable electrode, and a slide plate 16 having a slide portion 10 whose edges are shaped like a square. Movable frame 7
On the lower surface, there is a molded part 12 that slidably engages with the V-shaped slide part 10 of the slide plate 16, a protrusion 11a that acts as a stopper when removing the movable electrode 4, and a protrusion 11a that acts as a guide when attaching the movable electrode 4. An engaging plate 15 having a guide portion 11b is fixed thereto. Note that the reference numeral 17 in FIG. 1B indicates a fixed electrode. As is clear from the illustration, the movable frame 7 and the link 8 are fixed at one position corresponding to the center of gravity of the three movable electrodes 4, and therefore the three movable electrodes 4 are in a balanced state. It will be suspended. Therefore, the load of the movable electrode 4 is no longer applied to the column 5 via the movable frame guide 6.

作の障害になることはない。 When the slide plate 16 is pulled out all the way to the front, the rear wall (not shown) of the letter-shaped slide part 10 engages with the stopper protrusion 11a and stops, so it is possible to prevent the movable electrode 4 from falling off due to slide inertia. The movable electrode 4 is disengaged from the protrusion 11a by a slight upward lifting operation by the operator.
can be removed. Furthermore, when attaching the movable electrode 4, the rear wall of the V-shaped slide portion 10 of the slide plate 16 is placed on the guide portion 11b of the molded portion 12 of the engagement plate 15, and then the movable electrode 4 is pushed in using the handle 13. be exposed. In the above-described operation of attaching and detaching the movable electrode 4, the column 5 supporting the movable electrode 4 is located at the back of the movable electrode 4, so that it does not interfere with the operation.
