Abstract

1,059,340. Magnetic switches. STANDARD TELEPHONES & CABLES Ltd. Nov.19, 1963, No. 45600/63. Heading H2B. A plurality of sealed magnetic contact units arranged side by side, are spaced apart by a magnetic member which prevents inadvertent operation by a permanent magnet of more contact units than it is desired to operate. As shown, the units 1 are inserted in slots 5 in a magnetic ring 4 and are separated by projections of the ring so that only one unit will be operated at a time by a rotatable magnet 3. In an alternative arrangement the contact units are spaced apart by bars of magnetic material. In other embodiments the contact units are mounted in a row. The bars or ring of magnetic material may be laminated. The magnet may actuate a plurality of rows of contact units, or a plurality of rows of units may be actuated by a plurality of magnets which are movable together. The magnets may be designed to move clear of the contact units so that the switch acts as a selector switch. Each magnet may operate a plurality of contacts of a row simultaneously.
