Abstract

576,861. Electromagnetic relays. ELECTRO METHODS, Ltd., and SCHUSTER, H. L. May 15, 1944, No. 9233. [Class 38 (v)] A member 2 of magnetic material is pivoted at its centre 6 to a fixed member 1 also of magnetic material and is repelled from it when the energization of a coil 27 causes both members to be magnetized with similar polarity. In the form shown the member 2 carries a contact 22 adapted to dip into mercury 25. Gravity returns the member 2 and a spring 23 conducts current to it from a terminal 4. Specification 525,779 is referred to.
