<p><P>PROBLEM TO BE SOLVED: To provide a miniature switch for DC cutoff with arc-extinguishing device, capable of implementing complete arc-extinguishing by eliminating unstable factors of a system of implementing arc-extinguishing by extending an arc with magnetic fields or the like. <P>SOLUTION: In the miniature switch for DC cutoff with arc-extinguishing device, a shielding plate 11 made of material having insulation properties and heat resistance is inserted between a stationary contact 4 and a movable contact 8 of a movable armature 6 and, by controlling a direction of mechanically pulling arcs, arcs generated during DC cutoff are completely extinguished and shut down. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
