【実用新案登録請求の範囲】[Scope of utility model registration request] 対向する可動・固定接触子のいずれか一方にその接触面
に向って軸方向の貫通孔を有し、開極時この貫通孔内を
接触面に向って高速流を生ぜしめ開極アークを吹き消す
接点開閉装置に於いて一方の接触子側にあって而も他方
の接触子の貫通孔に開極時挿入される先細状の突起を形
成したことを特徴とする接点開閉装置。One of the opposing movable and fixed contacts has a through hole in the axial direction toward the contact surface, and when the contact is opened, a high-speed flow is generated inside this through hole toward the contact surface and an opening arc is blown. A contact opening/closing device characterized in that a tapered protrusion is formed on one contact side of the contact switching device and inserted into a through hole of the other contact when the contact is opened.
