Abstract

682,330. Snap-action switches. SHARP, W. Aug. 17, 1950 [Sept. 2, 1949; Nov. 12, 1949], Nos. 22737/49 and 29029/49. Class 38 (v) The movable contact carrier A is rotatably mounted by trunnion pins 8, 18 in the lid of the switch box and consists of two parts 5 which clamp between them a number of cartridge fuses 3 and are themselves held in position by socket members or end caps 6, 7. The cap 7 is permanently rotatably mounted in the right hand side of the lid, Fig. 1, and is controlled by a dead-centre snap spring 14. The cap 6 has a trunnion 8 slidably engaging the left hand side of the lid and is controlled by a spring 11 so that it may be moved to allow the carrier A to be detached and the fuses replaced. The trunnion 18 of the cap 7 carries a pin 21, engageable with lost motion by a notch 20 in the operating lever 19. The lever 19 also has a flange 23 co-operating with a pin 22 on the switch box to prevent removal of the lid when the switch is "on". The fuses 3 each bridge two spring contacts 2.
