Abstract
1285351 Movable magnet switches COMMUNICATIONS PATENTS Ltd 12 March 1970 [14 March 1969] 13463/69 Heading HIN The reed contact units 17 of a rotary switch are each disposed in a channel of conductive material which includes two magnetically permeable members arranged one on each side of the contact unit to provide electrostatic and electromagnetic screening of the contact unit. The rotary selector switch if formed with a laminated assembly of a non-magnetic metal mounting plate 1, an insulating plate 2, an insulating plate 3 (coated with a conductive non- magnetic layer) an insulating plate 4 and a printed circuit board 5 with an earthed non- magnetic conductive layer on one side and printed circuit connectors 45, 46 on the other side. The connectors 45 extend from a contact area 6 of the board 5 to the outer terminals 32 of the vertical array of reed units 17 and earthed connectors 46 extend between the connectors 45. The contact units 17 are mounted between magnetic wires 19 on an aluminium ring 18. The inner terminals of the contact units 17 are attached to a common disc 35 through.which a shaft 13 extends. The shaft 13 is driven from an electromagnet and ratchet and pawl device 14 and moves an arm 12 so that a magnet 11 influences the contact units 17. A non-magnetic cover 10 over the contact units also acts as an eddy current brake for the magnet 11.
