Abstract

This electrical supply rail enables electric light bulbs or any other current-consuming elements to be supplied. It comprises an upper conducting strip (10) and a lower conducting strip (30) which are separated by an insulating body (20) and fitted at regular intervals with small projecting plates (11,31; 131), the free end of which is capable of supplying one pole of the current-consuming element (50, 70). The upper conducting strip comprises transverse slots (13) allowing the small plates projecting from the lower strip to pass freely. These conducting strips may be slid into an insulating rail (40). In addition, a fitting clip 80 enables the contact loops (71, 72) for the Xenon light bulbs (70) to be housed between elastic arms (84 to 86). <IMAGE>
