Abstract

1322434 Magnetic switches SUWA SEIKOSHA KK 9 Aug 1971 [17 Aug 1970 7 Sept 1970 12 Nov 1970 25 Nov 1970] 37317/71 Heading H1N A switchboard has a plurality of sealed magnetic reed contact units mounted substantially in one plane and operable by an external permanent magnet. The contact units 3 may be mounted within a flat board 8 marked to indicate the positions of the contact units. Locating frames (Fig. 6, not shown) may be provided to position the permanent magnet on the board and the board may be provided with a resilient core (not shown), into which the magnet has to be pushed to effect operation. Fig. 9 shows a permanent magnet movable in the direction of its magnetic axis which is normal to the major axis of the contact unit and adjacent one end thereof.
