Abstract

480,281. Electromagnetic switches. STANDARD TELEPHONES & CABLES, Ltd., WRIGHT, E. P. G., and BOWSHER, E. A. H. Aug. 21, 1936, No. 23069. [Class 38 (v)] [Also in Group XXXIX] The interrupter contacts 36 of a step-by-step switch, which are carried respectively by a support 31, and a flexible strip 41, are controlled by a U-shaped member 30 pivoted to the support 31 by a pin 32, and connected thereto by a spring 37 of the form shown so that it operates with a snap action under the control of the magnet armature 33, which is forked to embrace a projection on the member 30.
