Abstract
1,033,475. Fluid actuation of switches. ROBERT BOSCH G.m.b.H. Aug. 4, 1964 [July 25, 1963], No. 30893/64. Heading H2B. Increasing pressure causes movement of a diaphragm 4 to operate switches 9 successively through independently movable plates 15, 16, on the diaphragm. The biasing springs 13 for the switching tongues 11 are adjustable via screws 14, while the plates 15, 16 have pins 18, 19, engaging the other sides of the tongues 11. Alternatively the diaphragm has a belt-shaped plate 20 and a disc-shaped plate 21 thereon (Fig. 3, not shown), the plates being independently movable to operate the switches via projections 29, 23, respectively, and the plate 21 having a central pin 25 guided in a bush 26 of plate 20 and a bore 27 of the housing 1. The switches operate with a snap action and may be normally open or normally closed.
