Abstract
1,202,146. Liquid-break switches. DOW CHEMICAL CO. 19 Feb., 1968, No. 7962/68. Heading H1N. A multiple contact slide bar switch having its contacts immersed in liquid, e.g. oil, includes one or more arrays of contact leaf assemblies 20 on a shaft 18 movable longitudinally between contact plates 12, 14 providing contact surfaces 26, 28, and spaced depressions 24 in surface 26. Each leaf assembly has a C-shaped element 92 on shaft 18 providing arms 98, 100, urged apart by springs 122, 124, and pressure bars 110, 112, to a limit imposed by a clamp element 102. When shaft 18 is moved, for example by a pneumatically driven piston 76 in an air cylinder assembly 78, the elements 92 interconnect or disconnect contact plate 14 and contact surfaces 126 between the depressions 24 of contact plate 12, surfaces 126 having bevelled edge surfaces 128 where arms 98 initially contact them. Oil is circulated through the switch via inlet 48 and outlet 50, and through the various arrays of contact leaf assemblies 20 via bores 54, 56. Plates 12, 14 are secured in liquid-tight manner to the frame 16, 32, by bolts 42, 44.
