Abstract

682,538. Fluid actuation of switches; switches held set and freed mechanically. AUTOMOTIVE PRODUCTS CO., Ltd. March 12, 1951 [March 31, 1950], No. 8170/50. Class 38 (v) [Also in Group XXXII] The fixed contacts 10, 11 of the switch are arranged to be bridged by flattening a dished metal disc 20 (see Group XXXII) e.g. upon increase of pressure in a hydraulic braking system. The contacts are embedded in an insulating block 12 with their faces flush with the surface of the block, and the disc 20 is clamped between the block and a rubber diaphragm 17, the disc so permanently engaging the contact 11. When the pressure drops again, the disc is restored to its dished condition by its own resilience. The disc may, alternatively, be flattened by a manuallyoperable cam or by a sliding member movable diametrally of the disc.
