Air break contactor with form-fitted parts

摘要

In an air break contactor, the armature comprises a first lamination and two second laminations, the first lamination having at a lower end an extension projecting at a 90 DEG angle with respect to the body of the lamination into a space between the bottom wall of the housing and the free end of a lower leg of the magnet assembly core member. The entire armature rests on an elbow of the lamination extension, while the second laminations are disposed between a pair of tabs extending from respective lateral edges of the first lamination.
