The auxiliary relays are electromechanical, attracted armature type, used in control and alarm circuits. There relays are designed as plug-in elements with the plug-in base having 14 terminals & 4CO per element. Each element is enclosed in a dust proof moulded, transparent, polycarbonate cover. There is no hard wiring between the relay element and the rear terminals on the base. This results in a compact rugged and reliable design. Radio metal is used for the magnetic components such as the armature, the core and the yoke of the auxiliary relay to ensure good electrical performance. The contacts are made from phosphor bronze and are nickel plated. The contact tips are of pure silver. The use of these materials ensures very good contact
