Abstract

1,103,118. Magnetic switches. W. DOUGLASS, and J. A. OLDING. 12 May, 1965 [13 Feb., 1964], No. 6007/64. Heading HlN. Sealed magnetic contact devices in cavities or on the outer surface of a cylinder are operated by a magnet on a double-acting piston in the cylinder. The piston is moved by fluid pressure differential. The contact units may be as described in Specification 1,103,116.
