A connecting system includes an electromagnetic switchgear, especially contactor, and a connector. In at least one embodiment, the system makes it easier to connect auxiliary and control lines. For this purpose, the connecting system, in at least one embodiment, includes at least one electromagnetic switchgear, especially a contactor. The switchgear includes a plurality of auxiliary contact connections and a coil connection terminal block. The coil connection terminal block is configured in such a manner that the coil connections lie in a plane with at least one auxiliary contact connection. The connecting system also includes, in at least one embodiment, a connector for simultaneously contacting the coil and auxiliary contact connections of one or more switchgears which connections lie in one plane. The connector has an internal wiring for electrically interconnecting the coil and/or auxiliary contact connections.
