To realize a novel circuit controller for an electric switch machine capable of preventing intrusion of a living thing such as ants and inhibiting occurrence of wear and dust caused by oscillation of a lever as much as possible while securing a space for the oscillation of the lever.SOLUTION: A circuit controller 2 includes a closing member 40 between a lever 22 and a lever projection port 18 of a cover part 12. The closing member 40 is inserted through an oscillation shaft 24 of the lever 22 projecting from a side surface of the cover part 12 to separate an oscillation space 60 of the lever 22 from an inside space 16. The closing member 40 has an upper member 41 and a lower member 42 which are combined to sandwich the lever 22 vertically. Gaps between the upper member 41 and the lower member 42 and between the lever 22 and the oscillation shaft 24 in the vicinity of the oscillation shaft 24 are set to satisfy a prescribed minute gap condition effective to inhibit intrusion of a living thing such as ants and intrusion of dust.SELECTED DRAWING: Figure 1

    【課題】レバーが揺動する空間を確保しつつ、蟻等の生物侵入を防止し、レバーの揺動に伴う摩耗や粉塵の発生をできる限り抑制する新たな電気転てつ機用の回路制御器を実現すること。【解決手段】回路制御器2は、レバー22とカバー部12のレバー突出口18との間に閉塞部材40を備える。閉塞部材40は、カバー部12の側面から突出したレバー22の揺動軸24を挿通して、レバー22の揺動空間60と器内空間16とを隔てる。閉塞部材40は、レバー22を上下に挟むように組み合わされる上方部材41および下方部材42を有する。揺動軸24付近において、上方部材41および下方部材42と、レバー22および揺動軸24との隙間は、蟻等の生物侵入および粉塵侵入の阻止に有効な所定の微小隙間条件を満たす間隔で構成されている。【選択図】図1
