Abstract
752,622. Electric selectors. STANDARD TELEPHONES & CABLES, Ltd. Sept. 17, 1954 [Sept. 25, 1953], No. 27007/54. Class 40 (4). A11 the contact sets in a cross-bar switch can be operated or returned to normal in any desired sequence by devices individually assigned to the contact sets. The switch is particularly applicable to signal indicator boards where a large number or even a majority of lamps may be lit at one time. Downward movement of a select bar VS places finger MF between a projection MH and an arm of a Geneva device UK so that subsequent movement of an operating bar HS rotates the Geneva device UK through a right angle. Attached to the Geneva device is a flat member BT so that alternate operations of the Geneva device close and open the contact set BF.
