<p>The coordinate switch, for a telephone exchange, has electromechanical coincidence relay as connecting element at a connection point. The relay is controlled via pulsed coils arranged in columns and rows. A permanent magnet (3) with armature (4) is located in the relay circuit (R) that lies parallel to a coincidence circuit (K). The coordinate switch is composed of coil strips. The coils in the columns are located at a distance above the coils in the rows. All parts such as U-bracket (1), yoke (2), magnet (3), armature (4), operating strip and contact springs are attached to the coil strips.</p> |
