Abstract

1,160,450. Mechanical switches. BUCHUNGSMASCHINENWERK KARL-MARXSTADT VEB. 7 Sept., 1966, No. 39935/66. Heading H1N. A matrix switch comprises a number of conductors 17 and co-operating spring wires 1 biased to engage the conductors but normally restrained by recesses 13 in plates 14. Selected wires, e.g. 1a, may be released from the recesses by setting slides (19), (Figs. 3, 4, not shown), which are slid to select the wire and tilted to operate it. All released wires are simultaneously disengaged from the conductor 17 by movement in the direction of the arrow of a plate 18 having an aperture for each wire, the wires being moved along the edges of plates 14 until they spring back into the recesses 13.
