Abstract

523,004. Automatic exchange switches. TELEFONAKTIEBOLAGET L. M. ERICSSON. Dec. 21, 1938, No: 37163. Convention date, Dec. 21, 1937. [Class 40 (iv)] A group of selectors sharing a bare-wire multiple are carried on base plates B supported on one side of a vertical plate A which supports an the other side insulating members I carrying the multiple wires. The ends N, P of the members I are shaped to co-operate with spaced apertures in the plate A and with slots in a cross-piece T adjustably carried by brackets. K on the plate A and provided with rubber packing M to ensure a tight fit. The plate A is integral with side plates F only one of which is shown, and the base plates B of the selectors are supported on ledges Q1, Q2. The base plate is pressed towards the multiple by a spring and its position in the transverse direction is determined by projections L1-3 which engage in slots in the plate A. The wipers BR1, BR2 enter the multiple through an extended opening in the plate A. The base plates B are slotted near the side plates F in order to localize the vibrations during the movement of the selectors.
