Abstract

638,849. Mechanical switches without quick action. DONOVAN ELECTRICAL CO., Ltd., and HAYWARD, W. H. July 19, 1948, No. 19282. Addition to 613,482. [Class 38 (v)] The switch-fuse of the parent Specification is modified in that the movable bridging- contacts 4 are carried by yokes 6 pivoted to links 7 pivoted to the base at 8. The upper yoke 6 is also connected to a link 9 connected by a further link 11 to the operating spindle 12. The lower yoke 6 is connected to the link 9 by a link 13 at a pivot 14 which is slidable in a slot 15 in the casing. On clockwise rotation of the spindle 12 the contacts 4 move simultaneously in an arcuate path about pivots 8 to bridge fixed contacts 1, 2.
