真空開閉器。 A cylindrical vacuum container having a supporting protrusion in the radial direction of an inner circumferential surface, a pair of fixed and movable electrodes housed in the vacuum container and capable of moving toward and away from each other, and a periphery of the pair of fixed and movable electrodes. a shield member disposed within the vacuum vessel to surround the pair of fixed and movable electrodes, and preventing a metal arc generated when the pair of fixed and movable electrodes are separated from adhering to the inner surface of the vacuum vessel; and an outer peripheral surface of the shield member. In a vacuum switch equipped with a ring-shaped shield holder welded to the support protrusion and supported by the supporting protrusion, the ring-shaped shield holder is formed by bending a thin plate material and spreads in the outer radial direction of the ring-shaped shield holder. A vacuum switch characterized by having a ring-shaped recess.
