Abstract

504,462. Mercury switches. WESTING- HOUSE BRAKE & SIGNAL CO., Ltd., KERSHAW, J. W. G., and SIMMONS, A. W. Oct. 26, 1937, No. 29099. [Class 38 (v)] In a tilting mercury switch comprising a tube 2, a movable body of mercury and a cup 4 through which an electrode 5 passes to make electrical connection with mercury 3 in the cup, a wall 6 surrounds the edge of the cup to reduce the difference between the angle of tilting of the switch necessary for the make and that for the break by facilitating the separation of the two bodies of mercury in the latter case.
