Abstract

1445621 Reciprocating generators GTE INTERNATIONAL Inc 9 Jan 1974 [30 Jan 1973] 4727/73 Heading H2A A push button operated signal generator has a yoke 3, with a plurality of limbs (3a, Fig. 3, not shown), each limb having a movable member 5 associated therewith forming a normally closed magnetic circuit including a permanent magnet, which circuit is broken by movement of member 5 on operating a selected button 2 in an array, thereby inducing a signal in a coil 14 wound on the corresponding limb (3a). The magnet provides the restoring force on the member 5 after release and may be either the fixed or moving member. For example, in Figs. 6, 7 (not shown) a single long bar magnet is used for a number of adjacent magnetic circuits. One leg of the yoke may be be replaced by a cranked magnet operating as the moving member 5 (Figs. 4, 5, not shown). The array may be used for telephone keying.
