を有することを特徴とする気中開閉器。 A stopper plate that follows the rotating shaft is attached to a rotating shaft that is rotated by an opening/closing lever provided on the outside of the switch box, and is part of a link mechanism that interlocks the rotating shaft and a movable contact. A locking portion is provided in which the front end surface of the stopper plate faces closely and locks the movable contact from opening when the movable contact is in the closed state,
The angle at which the locking portion of the link mechanism that contacts the stopper plate contacts the front end surface of the stopper plate is approximately a right angle, and the line of action of the force exerted by the locking portion on the stopper plate is such that the rotation of the stopper plate is made substantially perpendicular. The stopper plate is set to pass through the center of rotation or the vicinity thereof, and the stopper plate is rotatably fitted to the rotating shaft of the actuating plate, and is driven in the closing direction by the actuating plate that interlocks with the opening/closing lever. A pneumatic switch comprising: a joint portion; an elastic body that biases the stopper plate in a direction to engage the actuation plate; and a floating mechanism provided between the actuation plate and the link mechanism.
