FIELD: electrical engineering. SUBSTANCE: drive has electromagnetic member 7, movable member 8 secured for rotation around hinge joint 21, fixed contact 3, movable contact supporting lever 5 secured for rotation around hinge joint 22 and switching mechanism 9, formed by the stretched member located between movable member 8 and movable contact supporting lever 5. Hinge joint 21 of movable member 8 and hinge joint 22 of movable contact supporting lever 5 are positioned on the same side relative to electromagnetic member 7, and switching mechanism 9 is connected to movable member 8 in the intermediate point between hinge joint 21 of movable member 8 and end area 26 of movable member 8, at whose level magnetic attraction to electromagnetic member 7 is accomplished. EFFECT: improved design. |
