Abstract

1,203,413. Fluid actuation of switches. INERTIA SWITCH Ltd. 27 Sept., 1967 [28 Sept.,1966], No. 43439/66. Heading H1N. Pressure on a rubber diaphragm 5 moves a plunger 6 to operate microswitch 8 when the pressure is sufficient to overcome the attraction between a fixed magnet 1 and an armature 3 or moving magnet (2) carried by plunger 6. Plunger 6 may be magnetic or non-magnetic. In an alternative arrangement, switch 8 is operated at a pressure sufficient to overcome repulsion between two magnets (1, 2, Figs. 2, 4, 6). Magnet 1 is carried by a threaded sleeve 7 to adjust the operating pressure. Switch 8 is axially adjustable with respect to sleeve 7.
