PROBLEM TO BE SOLVED: To provide a current switch with reliability and economical efficiency, which can be assembled by surely adjusting the wipe and distance between electrodes within a common assembling difference by adjusting the wipe and the distance between electrodes irrespective of an axis direction length of a vessel. SOLUTION: Support parts 3b mechanically fastened to a flange 1a at an end part of the vessel 1 are fitted to opposing electrodes 3. Opposing arc electrode parts 3a are fitted to an inner periphery of the support parts 3b in a state that the fitting position in the axis direction of the vessel 1 is changeable. Further, stopper tools 6 for positioning and fixing the opposing arc electrodes 3a are fitted to the inner periphery part of the support parts 3b. COPYRIGHT: (C)2004,JPO
