Abstract

1,139,162. Magnetic switches. SHELLMEX & B.P. Ltd. 28 July, 1967 [18 Aug., 1966], No. 37103/66. Heading H1N. A pressure responsive switch has a permanent magnet 8 on a support 7 on a diaphragm which closes the upper end of a gas chamber 5. When it is moved on increase in pressure in the chamber 5 the magnet 8 acts on magnetic contacts 9. The operating pressure may be set by adjustment of a biasing spring 10 or of the distance between the contacts 8 and magnet 9. The level of fluid 2 in a tank controls the pressure in the chamber 5 and the operation of the contacts.
