Abstract

416,036. Actuation of switches. REES, C. L., and LUSH, G. R., 12, Priory Avenue, Hastings. March 6, 1933, No. 1155. [Class 38 (v).] A switch operated by the oil-pressure in the lubrication system of an engine, and adapted to operate with a very small pressure and yet withstand a large pressure, comprises a tube 5 connected to the oil system, a non- metallic oil-proof flexible diaphragm 3 adapted to be pressed upwards by the oil pressure, and a mushroom-shaped plunger 2 pressed upwards by the diaphragm to move a spring contact 8 into engagement with a fixed contact 7. The large head of the plunger 2 provides a support for the diaphragm in the "on" position, enabling it to withstand a high pressure. British Specifications 328,811, [Class 38 (v)], 352,144, and U.S.A. Specification 1,833,996 are referred to.
