Abstract
1321659 Pressure actuated switches FLOWSHEET PANELS Ltd 17 Aug 1971 [19 Sept 1970] 44767/70 Heading H1N [Also in Division G1] In a liquid level detector in which a tub 21 dips into liquid, the level of which is to be detected, the alteration of air pressure, within the tube 21 due to the alteration in the liquid level, deflects a diaphragm 22a to pivot a switch arm 22c between contacts 22f to actuate or otherwise a liquid supply pump 17.
