Abstract

708,464. Electromagnetic relays. INTERNATIONAL AERADIO, Ltd.. and JUCKER, J. Nov. 20, 1951 [Nov. 21, 1950], No. 27202/5). Class 38(5) In an electromagnetic relay with a contact spring ,pile up mounted at one end of a frame carrying the armature 4 at its other end the fixed contact blades 7a, 7b are supported, in grooves in an adjustable insulator 9 and the movable contact blades 6 in grooves in a lifting plate 8 fixed to the armature. The insulator 9 is supported on a threaded spindle and by varying its position the relaying function can be readily changed. In a modification. Fig. 7 (not shown), a biasing blade spring bears on the outer end of the plate 8.
