Abstract

848,513. Fluid actuation of switches. BENDIX-WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. July 1, 1958 [July 8, 1957], No. 21067/58. Class 38 (5). [Also in Groups XIX, XXIX and XXXIV] When the pressure in the reservoir of, e.g., a brake system, to which the nipple 23 is connected, exceeds a given minimum value a piston 30 of insulating material, e.g. hard rubber, is moved upwardly against the adjustable springs 32, 34 to separate a contact bush 48 from a contact 50.
