Claim:
Conductor line ( 2 ) for supplying at least one device ( 11 ) that can be moved along the conductor line ( 2 ), with a first elongated conductor lane ( 5 b ) and at least another second elongated conductor lane ( 6 b ), wherein the first ( 5 b ) and the second ( 6 b ) conductor lanes feature first ( 5 f ) and second ( 6 f ) contact openings, respectively, extending along the longitudinal direction of the respective lanes and serving for accommodating parts ( 15 a ; 16 a ) of first ( 15 ) and second ( 16 ) sliding contacts, respectively, of a collector ( 14 ) of the device ( 11 ), wherein the second contact opening ( 6 f ) of the second conductor lane ( 6 b ) is realized such that the first sliding contact ( 15 ) to be connected to the first conductor lane ( 5 b ) cannot engage into the second contact opening ( 6 f ) and therefore cannot be connected to the second conductor lane ( 9 ).
