Abstract: An arrangement in a conductor track, the conductor track having a connection groove extending in the longitudinal direction of the track for connecting devices to the conductor track by way of an adapter, current conductors arranged in the connection groove in the longitudinal direction thereof for supplying power by way of the adapter to the devices connected to the conductor track, and at least one signal conductor arranged in the conductor track for supplying by way of the adapter a control signal, such as a bus control signal, to the device connected to the conductor track. To achieve a simple and esthetically advantageous solution, at least one signal conductor is arranged in the connection groove of the conductor track, and a partition wall of electrically conductive material is arranged between the signal conductor and the current conductor.

Abstract: An arrangement in connection with a current take-off device of a contact rail system, comprising an adapter portion arranged to be connected to be removable electrically and mechanically to a contact rail, and conductors arranged inside the adapter portion and connected by means of slit edge connectors to contacts providing an electric connection for the adapter portion and the contact rail, by means of which conductors the current is conveyed from the adapter portion to an electrical apparatus to be connected thereto. To ensure an electric contact, at least one wall portion is arranged to a cover portion of the adapter portion at each slit edge connector, which wall portion is arranged to press the conductor into a slit of the slit edge connector when the cover portion is put in place.
