Abstract

1421511 Movable magnet switches AMF Inc 4 Jan 1974 [16 March 1973] 00470/74 Heading H1N A movable magnet switch has a magnet in the form of a sleeve or apertured piston 16 in a cylinder 21 and arranged to operate reed contact units 17, 18 when fluid flow between the ends 24 moves the sleeve against the action of springs 22 which bias it to the centre of the cylinder 21.
