Abstract
832,667. Magnetic switches. STANDARD TELEPHONES & CABLES Ltd. May 30, 1958 [May 31, 1957], No. 17353/58. Class 38 (5). A selector switch has a number of magnetic contact devices such as 1 ... 3, 8...10 in sealed envelopes, such as those of Specification 829,066, mounted in holes in magnetic strips 6, 13, 35, 36 and a magnetic cylinder 7. A rotatable shaft 17 coaxial with the cylinder carries a permanent magnet 29 arranged to bridge the gap between any strip and the cylinder 7 so as to operate the contact devices associated with that strip. Welded to the end of the cylinder 7 is a magnetic member 16 with arms 20 ... 23 which prevent the flux passing to the strips when the magnet is rotated into an intermediate position. Any number of contact devices may be used, and a second permanent magnet may be mounted on the other end of the shaft 17 either in line with or angularly-displaced from the first magnet. The shaft may be rotated by hand, by electro-mechanical means or by an electric motor through reduction gearing. In Fig. 4, pairs of strips 30a, 30b ... 30n, are arranged so that the magnet 31 can be moved adjacent any one of them to operate any of the sets of contact devices 1<SP>1</SP> ... n<SP>1</SP>. The operating member 34 may be latched by a spring 32 and restored by a spring 33.
