FIELD: electrical engineering. ^ SUBSTANCE: proposed mechanical switching contact designed for double-pole change-over has holder made of insulating material that accommodates fixed contacts alternately coming in contact with contact holder; the latter, in its turn, mounts on its loose end turning lever carrying on its end respective conducting contact member. Mechanical switching contact is made in the form of modular structural unit that can be arbitrarily assembled. It has minimal quantity of structural components for double-pole switching and can be easily built in load switch without additional adjustment and matching. ^ EFFECT: simplified design, reduced space requirement. ^ 4 cl, 4 dwg |
