A control switch for operating a crane. The control switch includes a first interface designed to transfer signals between the control switch and a control unit of the crane. In order to combine, in particular, the robustness and operating reliability of the control switch desired in industrial use with increased functional scope in a cost-effective way, the control switch is provided with a second interface designed to transfer signals between a mobile terminal and the control switch in order to add functions of the mobile terminal to the functional scope of the control switch.

Control switch

An arrangement is provided for connecting two successive contact line rails, each made of a longitudinal plastic profile and of at least one contact rail extending along the contact line rails. A contact rail connector is connected to the opposing ends of the contact rails of two successive contact line rails, electrically and mechanically connecting the contact rail ends of the contact rails, and having cover elements attached at the opposing rail ends of the contact line rails of two successive contact line rails, covering the contact rail connectors and displaceable relative to an intermediate element. In order to provide an arrangement for attaching two successive contact line rails that is simple to produce and allows uncomplicated assembly, the intermediate element is attached at each of the opposing rail ends of the contact line rails to be connected together, and the cover elements are attached to the intermediate elements.
