Abstract

486,937. Mercury switches. BEAR, P. S., and BUCKLEN, H. E. Dec. 7, 1936, No. 13058/38. Divided out of 486,770 under which a Specification was laid open to inspection under Sect. 91 of the Acts, June 7, 1937. [Class 38 (v)] A body of mercury 62, Fig. 1, is arranged on tilting to merge with a small body of mercury 58 thereby connecting an electrode 56 with an iron envelope 46 the parts being separated from each other by a ceramic member 49. A rubber cup 65 surrounds the ceramic member 49 and is pressed into sealing engagement by a disc 68 and ring 69 held in position by flanging over the end of the envelope as at 70. In the modification shown in Fig. 4, the ceramic member is extended to form a tube 83 containing a tubular electrode 87, and the rubber cup 64 is compressed against a shoulder 97 formed by compressing the envelope. In a further modification, the whole switch and connecting terminals are encased in moulded insulating material. Fillings of inert gas and insulating liquid may bo introduced by removing a screw 19. Specification 486,770 is referred to.
