Abstract RU 2367048 C1

FIELD: electrical engineering.

SUBSTANCE: invention relates to LV and HV electrical hardware and can be used in remote control circuitry. Proposed contactor comprises, preferably, three vacuum arc-extinguishing chambers, electromagnet, casing, insulating lever with electromagnet armature, insulating lever axle, yoke, opening spring, lever stroke limiter and set of auxiliary contacts furnished with a push-button. In compliance with this invention, aforesaid opening spring is centered by two elements, one is furnished with a rod and the other one is provided with the hole mating aforesaid rod. The elements are arranged to displace the rod inside the hole. Sizes of the centering elements allow their telescopic folding at spring compression. One of the said elements thrusts on the yoke, the other one on the stop screwed in the lever. Note that face surfaces of centering elements and those the said elements rest on represent a sphere and a conical seat.

EFFECT: ease of servicing due to quick-release spring.
