SWITCH

PROBLEM TO BE SOLVED: To solve the problem that a conventional switch for suppressing an arc from being generated in a case has a large-sized structure.SOLUTION: A switch 1 constituted by accommodating, in a container 11, one or two or more line switching circuits 12 having two charging parts 121, 122 arranged to face each other, and a connection part 123 connecting both the charging parts 121, 122 in an openable/closable state is provided with a barrier member 13 having a surface, facing at least the line switching circuit 12, made of an insulating material having properties of carbonizing by heating between the line switching circuit 12 and a lid body 113 of the container 11 (equivalent to a side wall of the container 11). This structure has the barrier member 13 arranged between the line switching circuit 12 and the side wall of the container 11, so the switch 1 capable of suitably preventing an arc from being generated can be made compact.SELECTED DRAWING: Figure 3 【課題】従来のケース内に発生するアークを抑制するための開閉器の構造は、開閉器が大型化するという問題があった。【解決手段】容器１１内に、互いに対向配置された２つの充電部１２１，１２２と両充電部１２１，１２２を開閉可能に接続する接続部１２３とを有する１又は２以上の線路開閉回路１２を収納してなる開閉器1は、線路開閉回路１２と容器１１の蓋体１１３(容器１１の側壁に相当）との間に少なくとも線路開閉回路１２に臨む面が加熱により炭化する性質を有する絶縁材からなる防壁部材１３が設けられている。線路開閉回路１２と容器１１の側壁との間に防壁部材１３を配設する構造であるので、アークの発生を好適に防止できる開閉器１の小型化が可能になる。【選択図】図３
