A multi-circuit switch, which is one of the equipment for power distribution lines,
For example, it is housed in a hand hole formed under the surface of the sidewalk. The hand hole is constructed of concrete or the like to have a predetermined mechanical strength, and is connected to the cable conduit through a cable hole provided in the side wall. A power distribution line is constructed by connecting the multi-circuit switch in the handhole to the cable installed in the cable conduit, and power is supplied by opening and closing the multi-circuit according to the load situation.

However, as conventional multi-circuit switches are designed to fit the capacity of the distribution line and are housed in handholes, manholes, etc., handholes, manholes, etc. are no longer necessary. Therefore, there is a limit to the reduction of construction costs.
Also, for example, some circuits have a grounding terminal in one of the multiple circuits, but when you want to ground any one circuit, you must connect it to this grounding terminal by turning on the corresponding switching contact. Therefore, the operation is troublesome, and furthermore, since the positions and locations of handholes, manholes, etc. are fixed, there are inconveniences such as restrictions even when it is desired to lay a bypass line in a desired section.
