Abstract

1454234 Movable magnet switches COMMUNICATIONS PATENTS Ltd 7 Feb 1975 [19 Feb 1974] 7410/74 Addition to 1285351 Heading H1N A selector switch as claimed in the parent specification has an optionally energizable electromagnet movable to operate the contact units. The electromagnet 15, 16 may have a ferrite core magnetizable by a current pulse in its surrounding coil or a permanent magnet which is neutralized whilst its surrounding coil is energized. The contact units are mounted on a conductive board 1 with terminals connected by respective resistors 11 to a common annular terminal 9 on a rear insulating plate 2. The electromagnet is mounted on an arm 13 on a rotatable shaft 14 providing conductive paths to the electromagnet coil via its outer conductive tube and insulated inner rod 17.
