Abstract

601,004. Magnetic switches. CIANCHI, A. L. Oct. 2, 1942, No. 13877. [Class 38 (v)] A switch E is held in one position by a stationary magnet F and moves to its other position when a movable controlling magnet C, carried by a float B approaches and neutralizes its influence. The switch E is of a kind. described in Specification 559,453. Other forms of switch may be used such as the mercury switches described in Specifications 485,259 and 493,355. There may also be two stationary magnets.
