Note that the same parts in each figure are given the same reference numerals. 1 “7 Mountains, 1- Figure 2 [Yo

Claims (1)

[Scope of utility model registration request] a second contact that opens and closes with respect to the first contact; a fixed outer cylinder that stores the first contact and forms a storage chamber in which insulating arc-extinguishing gas is filled; a negative pressure chamber that generates negative pressure in conjunction with the opening operation and sucks the insulating arc-extinguishing gas from the storage chamber; and a negative pressure chamber that is provided at the first contact and opens the first and second contacts. A switch comprising a magnet that generates a magnetic flux that intersects with an arc generated when the arc is released, and a leg of the arc on the first contact side is driven by interaction between the arc and the magnetic flux.
