Abstract

726,447. Automatic exchange switches. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Dec. 9, 1953 [March 14, 1953], No. 7132/53. Class 40 (4). A wiper member consists of a generally hairpin-shaped piece of wire 12 which is formed with its apex projecting out of the axial plane of its limbs to provide a contact tip. A wiper assembly comprises two such members joined by an insulating collar 15. The open end of each " hairpin " is either clamped between an insulating plate and a metal terminal plate, Figs. 1 and 2 (not shown), or embedded in a block of plastic material, an extension to one limb of the " hairpin " serving as a terminal, Figs. 4 and 5 (not shown).
