Abstract

629,286. Electromagnetic relays. TELEFONAKTIEBOLAGET L. M. ERICSSON. Nov. 20, 1945, No. 31253. Convention date, Nov. 22, 1944. [Class 38(v)] In a telephone relay, the armature 11 and flat core 13 are arranged in'perpendicular planes and the edges of the core are bent as at 15, 16, 17 and 18 to form pole pieces. The core may, as shown, be made of two stamped soft iron parts welded together and the armature may pivot about an edge 19. Alternatively projection on the armature may engage holes in the pole pieces to provide a joint.
