Description of the Related Art A switch for opening and closing an electric circuit includes a circuit breaker for opening and closing not only a normal current but also a large current generated at the time of an accident, and a disconnector for opening and closing a voltage. is there. Circuit breakers used in high-voltage circuits or special high-voltage circuits are designed to quickly eliminate arcs that occur when interrupting large currents at the time of an accident. 6 In many cases, the structure is sealed in a (sulfur hexafluoride) gas atmosphere. However, in a switch intended only to open and close a voltage, no arc is generated at the contact when switching the circuit. ,
Even when used in a high voltage circuit or a special high voltage circuit, it is often an open type structure. Also, when stored in a container, the material is stored in a metal container because the workability of the material is good and the price is low.

を生じてしまう。In the open type switch, the charging section is exposed, so that it is of course possible to install the switch alone outdoors, but even when the switch is housed in a switchboard, an electric shock may be inadvertently touched. In addition to ensuring that there is no gap, the insulation distance between the switchboard itself and various devices attached to the switchboard must be sufficiently ensured to prevent a grounding accident from occurring. For this reason, an open switch requires a sufficient space around the switch, so that the switchboard becomes large and disadvantages such as extra measures for preventing electric shock are required.

る。When this switch is housed in a metal container, the above-mentioned disadvantages can be avoided. However, terminals for connecting the housed switch and an external conductor are insulated from the metal container. Therefore, it is necessary to attach a bushing molded of, for example, a synthetic resin to the metallic container. In addition, since the metal container is directly attached to the switchboard, the switch housed inside the metal container and the metal container must have an insulation distance commensurate with the voltage, so that the container becomes large. There is. Further, since the switch must be insulated and attached to this container, the mounting structure is complicated and the container is disadvantageously further enlarged.
