The current can consist in that at the foot of the current guide rail has a cavity accessible against spring force by a longitudinal collector 5, in which a ble contact pin is provided, the two ropes of the current collector attached to the at least two conductors isolated from each other of the longitudinal slot are arranged, with one at the bottom of the cavity of the current while the current collector is a perpendicular to the guide rail arranged protective conductor in Kon current guide rail through the longitudinal slot der- io clock connection.
