An electromechanical connecting device can be connected to a switching device provided with switching magnets, arranged on a working carriage and connectable to a current source by means of current supply contacts, and can also be connected to a triggering device provided with triggering magnets and electrically connectable to a consumer. These switching magnets can be moved from a rest position to a working position against a restoring force, establishing a contact among pairs of contacts and thus an electric connection between the means of a special coding together with the triggering magnets arranged in the triggering device to generate particular magnetic fields for the switching process. In the switching device, at least one safety part designed as a safety magnet or ferromagnetic material can be moved in the direction of the triggering device from a rest position into a live position by a matching magnet or ferromagnetic part arranged in the triggering device, so that when the safety part returns to its rest position it causes a intentional short-circuit between the poles of the pair of contracts of the switching divide even when the triggering device is removed, whereas the working carriage remains in the live state.
