<p>A display system comprises a support (122) having at least one groove (121) therein, the groove being undercut on each side of the entrance thereto, goods display means such as shelving or racks being attachable to the support by engagement in the groove, a pair of electrical conductors (126) running along the inside of the groove wholly within the undercut portions thereof, means for establishing an electrical supply connection to each conductor, and coupling means (123 - 125) engageable in the groove at any point therealong to make an electrical connection to an electrical appliance (120) such as a lamp. The conductors (126) are preferably mounted on a liner for the groove by adhesive, co-extrusion or retaining ribs of a separate insert. The coupling means of the appliance (120) supports spring biassed contacts extending along a T-shaped foot that enters the narrow groove mouth, the coupling means then being rotated to engage the contacts. A cammed sleeve is rotated to lock the coupling means to the groove. <IMAGE></p> |
