Abstract

1338548 Electromagnetic relays BACH & CO 21 April 1972 [22 April 1971] 18749/72 Heading H1N An electromagnetic relay with at least one set of change-over contact springs 22, 24, 25 has its springs mounted in slots 32, 33, 31 in an insulating block 26 in which the contact mounting slots are inclined to a base surface 40 of the block in such a way as to determine the elastic preload of the engaged contact springs and the block 26 is also provided with projecting arms 41, 42 which are engaged by respective fixed contact springs 25, 24 when disengaged by spring 22. The relay has two change-over contact sets, one on each side of a wall 27 of the block 26 and the wall has a slot 50 in which an armature operated member is movable so that its arms 51 act on the movable contact springs.
