Abstract
1399940 Electromagnetic contactors SIEMENS AG 25 Aug 1972 [25 Aug 1971] 39862/72 Heading H1N An electromagnetic contactor has its contact carrier 5 attached to the armature 4 in such a way as to allow relative tilting movement, against the bias of springs 9, about an edge of a polygon (such as a rectangular surface 7) formed by points of engagement between the armature and carrier and arranged so that the tilt is limited by the springs to avoid engagement of the armature with a surface of the carrier other than that defined by said points. In Fig. 1, the armature extension 4 has a rectangular hole 8 through which a smaller rectangular bar, 6 attached to the carrier 5, extends and the surface 7 is formed on the bar 6. Four springs 9 act between the extension 5, and the carrier 5 and have lines of action outside the surface 7 so as to oppose tilting. Fig. 5, shows the rectangular surface 20 formed on the inside of the hole 8 and Fig. 7 shows how the surface can be limited by points 16 on a steel pad 15. Such a "pad" may be attached to the sides of the bar 6 (Figs. 8 and 9, not shown).
