の回路しや断器。[Claims for Utility Model Registration] (1) A plurality of arc-extinguishing plates arranged in the vicinity of at least one pair of contacts for switching on and off the load current and extinguishing the arc generated when the contacts are opened are arranged substantially parallel to each other at predetermined intervals. In the arc-extinguishing parts of circuit boards and circuit breakers arranged one on top of the other while maintaining insulation from each other, the front end of the arc-extinguishing plates at both ends, which faces the contact point of at least one of the arc-extinguishing plates, faces toward the center of the arc-extinguishing part, and each The L-shaped bent portion is formed with a predetermined interval between the front ends, and at least one arc-extinguishing plate is formed on the surface of at least one of the arc-extinguishing plates at both ends facing the other arc-extinguishing plate. A circuit switch or disconnector characterized by having a convex portion. (2) The above-mentioned convex portion is provided approximately at the center of the arc-extinguishing plates at both ends, and is a mountain-shaped convex portion parallel to the bending ridges of the L-shaped bent portion, as described in claim 1 of the utility model registration claim. circuit break or break.
