Claims

[Scope of utility model registration request]

In a switch that rotates and interrupts an arc caused by the separation of a pair of cylindrical electrodes that are provided in an arc-extinguishing fluid so that they can move toward and away from the arc, using the magnetic flux of a permanent magnet or a coil driven by an arc current. . A switch, wherein the one electrode is provided with an arc-wrapping insulator that protrudes from the inside of the one electrode into the inside of the other electrode and is freely retractable from the end face of the other electrode.
