13 47,615 A B S T R A C T ELECTRIC CONTROL DEVICE The invention relates to an electric control device, such as an electromagnetic contactor, relay or the like, including auxiliary contact means. The auxiliary contact means include stationary contact and terminal assemblies (29-33) supported in the insulating structure (1, 3) containing the operating coil of the device, and an auxiliary contact operating member (25) which is mounted in the insulating contact carrier (5) of the device as an integral part thereof sufficiently movable relative to the contact carrier to permit over- travel of the movable assembly (5, 8) following closure of the auxiliary contacts, the operating member (25) being spring-loaded in a contact-pressure providing sense. The novel auxiliary contact means are suitable for use with control devices too small or otherwise not adapted to utilize unitary interlocking assemblies, and also for increasing the interlocking capability of control devices which are designed to employ such unitary inter- locking assemblies.
