Abstract

651,923. Switch contacts. TELEFONAKTIEBOLAGET L.,M. ERICSSON. July 9, 1948, No. 18543. Convention date, July 14, 1947. [Class 38(v)] The individual springs 10 of a contact spring set, e.g. for an electromagnetic relay, have lateral tongues 52-54 and 62-64 on both edges adapted to engage holes 13, 14, 16, in two supporting side-plates 11, 12, the tongues preferably being turned over on the outside of the plates so as to secure the springs therein. The fixed springs have additional tongues 55 which engage loosely in holes 15 in the plates 11, 12, and also have'lugs 27 co-operating with teeth 17 formed on the plates. A fixing bracket 19, having tongues 20 engaging holes 18 in the side plates, has guiding holes 21 for a lifting bar 22 operable by an armature (not shown), and having slots 23 engaged by lugs 26 on the movable springs.
