Abstract

620,616. Switch contacts. STANDARD TELEPHONES & CABLES, Ltd., and TOWNER, S. H. Jan. 23, 1947, No. 2129. [Class 38(v)] Contacts springs 3 having locating shoulders 4 are fixed in through slots 2 in an insulating support 1 by injecting cement into the slots around the roots 6 of the contact springs. The roots may have slots 7 which protrude beyond the support to receive a D-shaped rod 11, Fig. 5, to lock the springs in position before injecting the cement. In a modification, Figs. 3, 4 (not shown, T-shaped metal pieces, apertured to coincide with the slots in the roots, are slid into the slots in the support from the opposite end and may be welded to the contact springs. Specifications 608,696 and 612,754 are referred to.
