Abstract
1,187,394. Fluid actuation of switches. SIMPLIFIX COUPLINGS. 10 July, 1967 [13 July, 1966], No. 31537/66. Heading H1N. A pressure switch includes a diaphragm 3, a piston 7 and a coil spring 9 coaxially mounted so that operation of a microswitch 12 occurs at a pressure determined by adjustment of the spring 9, by relative movement of casing parts 10 and 2, casing part 10 being screw-threaded at 11 on to casing part 2. Microswitch 12 is mounted on a support 13 screw-threaded at 14 to the casing part 10. Epoxy resin filling or plastics inserts or grub screws (not shown), lock the screw threads to secure parts 2, 10, 13 in the desired adjusted positions. A cover 15, Fig. 2 (not shown), encloses the end of the support bearing the microswitch 12. A shoulder 8 limits downward movement of piston 7, while upward movement of the piston under its spring loading is limited by the lesser diameter of the cavity 1c in the head la or by abutment against a spacer ring 5, Fig. 2 (not shown).
