式ガス開閉器。[Claims for Utility Model Registration] A pipe-shaped movable contact that is integrally provided with a piston that reciprocates within a cylinder in an arc-extinguishing gas atmosphere, and whose tip portion is led out from the end wall of the cylinder;
a suction chamber formed between the piston in the cylinder and the end wall; and a suction port formed in the base peripheral wall of the movable contact and interlocked with the suction chamber, and the tip of the movable contact. In a suction puffer type gas switch in which a portion of the piston is inserted into a fixed contact and is in contact with the fixed contact so as to be able to move toward and away from the fixed contact, a plurality of valves are connected to the suction chamber before the shutoff is completed in the vicinity of the shutoff completion position of the piston on the peripheral wall of the cylinder. A suction puffer type gas switch with an exhaust hole.
