Claims

【実用新案登録請求の範囲】[Scope of utility model registration request]

両側貫通の窓孔を有する絶縁物製の可動台と、両端が前
記窓孔より突出して可動接点を有する両端片及び中央を
固定接点側に突出した打出凹部とでなした可動接点板と
、この可動接点板の打出四部と前記窓孔の一方側面とに
弾圧されたコイルバネとでなり、而も前記可動接点板は
その接点離間時そのバネ圧にて打出凹部の上下端縁が前
記窓孔の他方内側面に局部的に当っており、他端縁から
突出した足が可動台の段面に当っていて可動接点板の上
下端縁と窓孔の上下面とは空間を介在し、而も接点接合
時可動台の進行によって前記一端縁を中心に凹側か回転
することを特徴とした両切型接点開閉装置。A movable contact plate made of an insulating material having a window hole penetrating both sides, a movable contact plate having both ends protruding from the window hole and having a movable contact, and a recessed part with the center protruding toward the fixed contact side; A coil spring is pressed against the four protruding parts of the movable contact plate and one side of the window hole, and when the movable contact plate separates its contacts, the spring pressure causes the upper and lower edges of the protruding recess to move toward the window hole. The other end is in partial contact with the inner surface, and the foot protruding from the other edge is in contact with the stepped surface of the movable base, and there is a space between the upper and lower end edges of the movable contact plate and the upper and lower surfaces of the window hole, and A double-cut type contact opening/closing device characterized in that the concave side rotates around the one end edge as the movable base advances when the contacts are joined.
