<p>The current rail system is supplied with current via a transformer, with lighting units (B) connected to it at a number of selected points. The relatively spaced current rails are incorporated in current rail sections joined together by linkages (A). Each of the lighting units may be secured to the current rail via a U-shaped clamp and a cooperating clamping screw, with a contact point on the inside of the clamp and at the end of the screw, for breaking the lacquer coatings for the opposing current rails to form electrical contact with the latter.</p> |
