Abstract
412,619. Automatic exchange switches. STANDARD TELEPHONES & CABLES, Ltd., SMITH, C. P., and NEWTON, G., Connaught House, Aldwych, London. Jan. 2, 1933, No. 12. Addition to 342,736. [Class 40 (iv).] The wipers of a rotary switch comprise two sheet metal strips embossed at 3 and riveted together at 4, the ends 5 being off-set and bent inwardly to form trailing tips 7 engaging opposite sides of the bank terminals. The wipers may be double-ended, and the strips may also be riveted together near the hub. Instead of being embossed, the strips may be formed with longitudinal ribs or may be of channel-section.
