Abstract

562,339. Electromagnetic switches. STANDARD TELEPHONES & CABLES, Ltd., TOWNER, S. H., and CHILDS, P. A. Dec. 23, 1942,No. 18227. [Class 38 (v)] An electromagnetic switch having a core 1, carrying a winding, and a yoke 5 has a U-shaped polepiece 2 attached to the core 1 (or to the yoke 5) and enclosing within its arms a polepiece 4 attached to the yoke (or the core) as well as the adjustable armature 7 which is mounted on a reed 6. The armature is moved along the reed for tuning it to the required frequency.
