Abstract: An electromagnetic contactor is fitted with an electromagnet sensitive to overcurrents, to cause the limitation and cut-off of excess currents.A movable contact bridge is controlled by a spring which holds it against the fixed contacts, and is struck by at least one component which is not connected to it, and which is positioned between it and the armature of the control electromagnet.

Abstract: Associable coupling connector for each of the storage relays of a sequential automatic device.The coupling connector comprises on the one hand the pins placed at the back of sockets which are assembled in three different areas of the front face, allotted respectively to the relay, to the input signals and to the output signals and, on the other hand, transversal conductors and transversal terminals to receive and transmit the voltage from the supply and the return to zero signal and respectively to transmit the sequential signals from the coupling connectors to the next ones.
