Abstract

1467721 Contact spring assembly TELEFONAKTIEBOLAGET LM ERICSSON 11 April 1974 [12 April 1973] 16384/74 Heading H1N In a contact spring set arrangement for an electromagnetic relay having make contact pairs, 10a, 10b, la, 1b on respective contact springs held at their one ends in a contact block 9 on the relay yoke 8, a double armed lever 4 linked with two combs 2, 3 pivots about a fulcrum bearing on a guide bar 5 fixed to the contact block, in such a way that when the relay armature 6 is moved displacing one comb 3 upwards the lever pivots to displace the other comb 2 downwards, projections 2a, 2b, 3a, 3b on the combs carrying respective spring blades 1a 10a, 1b, 10b, with them causing contact between the contact pairs to be made without vibration.
