Abstract

1388845 Movable magnet switches RONALD TRIST CONTROLS Ltd 19 June 1972 [21 July 1971] 34250/71 Heading H1N A magnetic switch with a movable magnet 14 carried by a pivotally mounted member such as a float 13 or paddle (not shown) has a mounting plate 1 arranged to be fixed to a container wall (not shown) to seal an aperture therein and having a non-magnetic tube 2 sealed therein at two annular rings 3 and extending so that a magnetic reed contact limit 7 in the tube is influenced by the magnet 14.
