Abstract
1,092,125. Electric selectors. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 18, 1965 [Feb. 18, 1964], No. 7134/65. Heading H1L. [Also in Division H2] Two or more sealed magnetic reed contact units, actuated by coincident pulses through their operating windings, are retained actuated by a magnetic circuit which includes one or more permanent magnets and the contact units in series. The contacts may be released by a reverse pulse through any one of the operating windings, so that by thereby opening one pair of contacts, the magnetic circuit is sufficiently weakened for all the other contacts to release. Pairs of such contact units may be arranged at the cross-points of a co-ordinate array for selective operation. In this case they may be released by a common auxiliary winding, several of which, associated with different cross-points of the selector, may be connected for simultaneous energization.
