Abstract

391,151. Automatic exchange switches. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, and SAXBY, R. N., 36, Millersdale Road, Mossley Hill, both in Liverpool. Oct. 14, 1931, No. 29409/32. Divided on 391,123. Drawings to Specification. [Class 40 (iv).] A bi-directional switch has the stepping magnets arranged in the same horizontal plane and all the mechanically operated spring sets in a second horizontal plane. The switch is identical in construction with that described in Specification 391,123, but the claims refer to (i) the use of the vertical magnet to provide rotary release, and (ii) the provision for direct release if release is initiated before rotation of the wipers has been effected and rectangular release if the switch is released at a large stage.
