Abstract

1,200,269. Polarized electromagnetic relays. TELEPHONE MFG. CO. Ltd. 29 April, 1969 [2 May, 1968], No. 20892/68. Heading H1N. A polarized electromagnetic relay having a sealed reed contact unit 5 surrounded by an operating coil 6 has first and second contact posts 14, 15 projecting outwardly from the contact unit and each adjacent a respective pole of a permanent bar magnet 8 which is engaged at spaced points by a spring 11 or springs which is or are adjustable to vary the position of the magnet relative to the contact posts 14, 15. The change-over contact unit 5 has mercury-wetted contacts and is located in a coil former 1 which has projections 2, 3 for magnet and spring-securing screws 7, 9. The spring forces on the magnet may be adjusted to set the magnet position, by means of a screw 10 engaging a spring stiffener 12 and the magnet is then clamped by the screw 7 or by varnish. The relay may be encapsulated within a shielding casing 16 which may be provided with holes allowing access to the adjustment screws. The position of the magnet 8 may be set to make the relay bi-stable or stable in one contact position only (Figs. 4 and 5, not shown).
