Abstract
543,193. Electromagnetic switches. CRABTREE & CO., Ltd., J. A., McLOUGHLIN, H. F., HILL, W. E. Aug. 12, 1940, No. 12868. [Class 38 (v)] A contact strip d mounted on the armature carrier h pivoted to a switch base b at its lower end, is adapted, when the switch is opened, first to form a "micro-gap" between the lower end d' and a fixed contact a, and, on fully opening; to separate the upper end d' from the upper contact a by an isolating distance. The strips d may be rigid and resiliently carried on the carrier, as by U-shaped strips the ends f<SP>1</SP> of which are bridged by a pin e retaining the strip d by presure of a spring g mounted between the loop of the U and the end of a recess g' on the carrier.
