Abstract

743,705. Electromagnetic relays. SANGAMO WESTON, Ltd. June 24, 1952. [Sept. 15, 1951], No. 15909/52. Class 38(5) In a moving coil relay the pointer 36 of the relay carries a contact 37 of magnetic material which cooperates with contacts 40, 40<SP>1</SP> of magnetic material disposed in the magnetic field from the permanent magnet 21 of the relay. The magnet 21 is magnetized laterally and the moving coil of the relay (not shown) is mounted round it and carries the pointer 36. The contacts 40, 41<SP>1</SP> are mounted on the base so as to be slightly adjustable. For separating the contacts after engagement, a slide 65 is provided in the relay cover. The slide may be operated by hand or electromagnetically so that an abutment 74 or 75 engages the pointer and separates the contacts. The slide may then be, left in this position and will serve to prevent re-engagement of the contacts (37, 40 say) that have just been separated while allowing engagement of the contacts 37<SP>1</SP>, 40<SP>1</SP>.
