Abstract

1,040,423. Fluid actuation of switches. BERG AIRLECTRO PRODUCTS CO. Feb. 27, 1963 [Aug. 17, 1962], No. 7938/63. Heading H2B. In a fluid pressure-operated snap-action switch, a diaphragm 36 moved by pressure from an inlet 15, presses against a freely-seated snap-action, dished-shaped disc member 28 until the pressure exceeds a predetermined amount, when the member 28 snaps over centre and pushes element 24 into bridging contact with ends 22 of terminal posts 16, 18. When the pressure decreases the member 28 resumes its original form and a spring 26 urges element 24 out of engagement with posts 16, 18.
