Abstract

535,643. Contact members for switches. McNEIL, W. A., PAILIN, G., and FERGUSON, PAILIN, Ltd. May 31, 1940, No. 9569. [Class 38 (v)] A contact-arrangement suitable for oilswitches, comprises a pair of replaceable tips 5, 6 with inclined inner faces 7, and a pair of contact fingers 12, 13 pivoted at 14 to side plates 9 of a U-shaped movable bridging member. The fingers are biassed against stops 19 by springs 15 seating on a block 16 pivoted at 18 between the plates 9, so that when the lift-rod is raised, the contact-pressure in the initial contact-making position 12<11> is considerable and increases towards the fully-closed position 12<1>. In the closed position, electrodynamic forces re-inforce the pressure, assisted by the action of those forces on the strap 20 connected between the tails 12a, 13a.
