. The Bell System technical journal . ts, for the location of wire subassemblies relativeto other relay parts and for the pretensioned restoring spring which inturn locates the actuating card in relation to the operating card determines contact separation of all twin moving contactsin relation to their respective single stationary contacts. Due to thesecontrols, and because the pre-deflected twin wire springs require noadjustment of contact force, no factory adjustments are anticipatedexcept on relays which fall outside acceptable limits for back tensionor contact gauging (or follow) as assembled. If necessary, therefore, therestoring spring may be adjusted to control the armature back gauging may be controlled if required by independent massadjustment of the single wire contact rows. Fig. 11 shows this operationbeing performed by bending the bracket arm using a tool designed forthis purpose. The mass adjustment feature is expected to simplify fieldmaintenance practice.
