Abstract

605,422. Electromagnetic relays. TELEFON FABRIK AUTOMATIC AKTIESELSKABET Dec. 21, 1945, No. 34811. Convention date, Dec. 15, 1941. [Class 38 (v)] In a polarised telegraphic relay having a permanent magnet 4 arranged between coils 2, 3 mounted on a U- shaped core 1, and an armature 6 mounted on a knife edge 7 at the top of the magnet 4, the contacts 8, 9, carried by the armature and adapted to engage alternately fixed contacts 10, 11, are mounted on a resilient bow 12, the centre of which frictionally engages the top of the armature so as to suppress vibration when the contacts engage.
