Abstract

1446558 Electromagnetic relays; switch contacts BUNKER RAMO CORP 15 Nov 1973 [15 Nov 1972] 53169/73 Heading H1N A switching device comprises a change-over contact assembly comprising fixed contacts 3, 4, and two resilient contact arms 31, 32 each having an unstressed form in the shape of an arc and bendable to assume a substantially straight line in its stressed assembled form within the switching device. Each contact arm 31, 32 is bifurcated, the assembly of the arms 31, 32 being formed from a single sheet of material, Fig. 4 (not shown), by bending about its axis of symmetry. One blade of each bifurcated arm 31 or 32 may be supported at a position 21, Fig. 3 (not shown), nearer the contact end of the blade than the support for the other blade to vary its properties. The resilient contact arm portion may be of beryllium bronze and the terminal portion 8, 9 of brass. The switching device described is an electromagnetic relay with coil 15, pole pieces 23, 24, and armature 16 biased by spring 14 and moving the contacts by U- shaped piece 13, the armature being shown in its de-energized position.
