Abstract

647,618. Electromagnetic relays. TELEFONAKTIEBOLAGET L. M. ERICSSON. Sept. 28, 1948, No. 25270. Convention date, Oct. 9, 1947. [Class 38(v)] The armature 34 of a relay transmits its movement to one or more contact-spring pile-ups 36 through an intermediate lever .39 the multiplication factor of which is varied by an adjustable stud 42 slidable along a groove in the lever 39. The stud 42 engages the top surface of a member 41 fixed to the armature and adjustable screws 40 on the lever 39 act on the lifting pins 37 of the pile-ups 36.
