<p>The housing contains the system magnetic core, armature and coil (28, 30), together with the contractor switching members. The armature yoke back points towards the cover. On the latter are formed protrusions (34) reaching down to the coil, whose coils touch the coil-former (30), thus holding it in the magnetic core. Preferably the protrusion ends carry spring elements pressing against the coil-former. Alternately these ends may have recesses (36) holding the spring elements, which may be of soft-elastic plastics. The elements may be cylindrical and fit into the recess blind bore. If the elements are hollow, they may fit over studs formed in the recess bottom.</p> |
