Abstract
772,008. Electromagnetic relays. ERICSSON TELEPHONES, Ltd., and DISTIN, L. S. Dec. 3, 1954 [Dec. 5,1953], No. 33881/53. Class 38(5) Cantilever contact blades 21 on an insulating member 18 pivoted at X engage fixed contacts 23 when the member 18 is oscillated electromagnetically as in the polarized relay disclosed in Specification 695,664. To ensure adequate contact pressure between each contact pair in the event of uneven wear amongst the pairs, each blade 21, after it has engaged its fixed contact 23, is engaged by a projection 35 on the member 18, whereby further movement of the member 18 causes the blade to flex about the projection instead of about its root end. The projections may be integral with the member 18 or may be separate parts adjustably mounted on the member. Plates 36 spaced from the blades 21 prevent undesired blade vibration.
