Abstract
441,342. Electromagnetic switches. C.A.V.-Bosch, Ltd., GLASER, W. H., and WOOD, N. R., Warple Way, Acton, London. July 17, 1934, No. 20925. [Class 38 (v)] In a cut-out device for use in a dynamo-battery system on a motor-vehicle, of the kind in which main contacts a, d and auxiliary contacts b, e are separable in succession under the control of an electromagnet g having the usual current and voltage windings j, k, a resistance i, inserted between the fixed main and auxiliary contacts to reduce sparking, is wound on the core of the controlling electromagnet, so that it also serves to accelerate the separation of the contacts.
