Abstract

1477892 Fluid actuation of switches INDUSTRIAS COPRECI SCI 1 Aug 1974 [13 Aug 1973] 34023/74 Heading H1N A multiple, fluid-pressure operated switching device comprises a plurality of switch modules each comprising a housing 11, 12 or 13, an adjustable diaphragm 8, 9 or 10, and a switching element such as 14 which engages its associated diaphragm, wherein each diaphragm forms at least part of one wall of a pressure chamber of its associated module, and wherein a single cover 4 common to all said modules is provided with partitions 17 to 20 which form further chamber-defining walls and has passages 17 to 20 arranged for connection to a source of fluid pressure. Each switch unit has calibrating means 15.
