Abstract

536,614. Magnetic switches. STANDARD TELEPHONE & CABLES, LTD. (Deakin, G.). Nov. 14, 1939, No. 30037. [Class 38 (v)] A rotating bar magnet 4 driven by a motor 2 causes the successive actuation of a number of armatures 7 pivoted on a ring 5 magnetized axially as shown and the corresponding movement of a number of contact springs 8 which bear on the armatures. In the form shown, the armatures, which are normally pressed to the left by the springs 8, are repelled in turn by the magnet 4 causing the contacts 8 to engage a ring contact 11.
