Abstract
774,832. Electromagnetic relays. COMPAGNIE INDUSTRIELLE DES TELEPHONES. April 7, 1955 [April 7, 1954], No. 10234/55. Class 38(5) Energization of a coil 4 causes attraction of a plate armature 6 pivoted, by lugs 7 (only one shown) whereby an insulating bar 11 carried on the free end of the armature moves contact springs 21 away from their respective fixed contact blades 22 and permits the contact springs 23 to move under their own resilience against the blades 22. Three contact sets 21 ... 23 are arranged side-by-side (Figs. 3, 4, not shown). The contact-carrying stack comprises insulating blocks 16 ... 19 mounted on the magnet frame 1. The armature is returned by a plate spring 24.
