Abstract

739,376. Automatic exchange switches. ERICSSON TELEPHONES Ltd., and MELTON, H. J. March 4, 1953 [March 4, 1952], No. 5581/52. Class 40 (4). Pairs of contacts 6, 8, which may be set in a contact bank of the type described in Specification 685,223, are actuated in turn by an insulated bead or roller 10 carried by a rotating arm 11. The contacts may be of the make, break, or change-over type, and the movable contacts 8 may be multipled, consisting of projections from a ring 7. The arm 11 is resilient and normally rests against a rigid arm 12.
