Abstract

958,732. Fluid actuation of switches. K. F. KOW. July 10, 1962, No. 26468/62. Heading H2B. One or more mercury tubes 7 mounted in a holder 6 on a rocker shaft 3 are actuated with a snap action by an operating shaft 5 via a spring toggle mechanism 20, 21. The shaft 5 has a stop 25 and is actuated by a handle which may be connected to a liquid-level responsive float.
