Abstract

1339855 Electromagnetic contactors SQUARE D CO 8 Dec 1971 [18 Dec 1970] 57106/71 Heading H1N The core and yoke and the coils 88 of an electromagnetic contactor are mounted and positioned by means of two members 116, 118 which also serve to guide the armature (not shown). The members 116, 118, also have holes 138 to receive projections 150 of the coil which is mounted as described in Specification 1,339,854.
