Abstract

580,634. Switches, partly electromagnetic. COOKE & FERGUSON, Ltd., and BUTTREY, R. N. July 15, 1944, No. 13561. [Class 38 (v)] A movable-rod contact a slidable in a contact b and co-operating with a circuit-interrupting socket contact c, is screened against the electrodynamic blow-off effects x of the current-loop, by means of a magnetic ring d wholly or partly surrounding contact c and a part-ring e associated with the contact b,
