Abstract
1402171 Electromagnetic cross-bar switches GTE AUTOMATIC ELECTRIC LABORATORIES Inc 28 July 1972 [29 July 1971] 35526/72 Headings H1L and H1N A cross-bar switch has a printed wiring card 10, a first plurality of spaced parallel bus-bars, such as 24, each provided at one edge with a plurality of fixed contacts 28 and at the opposite edge with projecting tags 30 engaging circuit portions 20 of the printed wiring card 10, a second plurality of spaced parallel bus-bars, such as 26, normal to the first plurality of busbars and each provided with a plurality of «safety pin» type movable contact members 34 and tabs 32 engaging respective circuit portions of the card 10. The contact members 34 are controlled by two orthogonal sets of select bars (42 shown from one set, and 44 from the other) arranged so that a contact 34 moved by a bar from each set will engage in the V-notch 28a of the fixed contact 28. Bus-bars 24, 26 are mounted in different level slots in a guide frame 22 which has notched portions 40 aligned with similar portions 40 on a frame 38 to guide the select bars 42, 44, which are notched at 84 to receive the ends of bias springs 52 of a common member mounted on the frame 38. The select bars are controlled by electromagnets 56 having cores and yokes formed from a common member 58, secured to the board 10, and pivoted armatures 66 biased by a common spring member 68 and provided with extensions 82 engaged in notches 50 in the ends of the select bars.
