Abstract

1,103,548. Magnetic switches. AVERYHARDOLL Ltd., and SPERRY GYROSCOPE CO. Ltd. 27 May, 1965 [1 April, 1964], No. 13374/64. Heading HlN. Sealed magnetic contact devices 5 are arranged in rows and selectively operated when a " key " containing magnetic inserts is placed in a slot 10 so that the inserts carry the flux from corresponding permanent magnets 8 to the contact devices. Different keys operate different sets of contacts to control the petrol supply to tankers and the keys may also be recessed to operate mechanical contacts such as micro-switches.
