Abstract

1291525 Magnetic switches; electric selectors PLESSEY CO Ltd 1 June 1971 [26 June 1970] 31151/70 Headings H1L and H1N A cross-bar switch arrangement has reed contact units which are operated when both magnets 3, 4 on its crossed movable row and column members 1, 2 are moved toward the contact unit and the contact unit is maintained in the operated position when the magnets return to their normal position but is permitted to reset when the magnets 3, 4 are moved further from the contact unit. The column and row members may be moved by electromagnets CEM 1 , REM 1 &c. and biased by springs RS 1 , CS 1 &c. Adjacent bars can be gauged together and/or the bars may be rotated rather than moved rectilinearly (Figs. 4 to 7, not shown).
