Sliding element system which includes a single support rod defining two mutually insulated electrically conductive paths

A sliding element system comprising

• at least one sliding element (2),
• at least one supporting element (4) extending in a displacement direction,
• at least one sliding element fitting (6, 8) holding the sliding element (2) and being displaceable along the at least one supporting element (4),
• the sliding element (2) being formed of at least partially transparent material and including at least two transparent conducting current paths (10,12) part, which substantially invisibly supply power to a power consumer (14) of the sliding element (2), the transparent current paths (10,12) of the sliding element (2) being supplied with power via the at least one sliding element fitting (6, 8), said at least one supporting element (4) defining two electrically conductive paths in mutually insulated relationship to each other, the supporting element (4) including at least one supporting rod (16), and the at least one sliding element fitting (6, 8) taps off power from said two mutually insulated electrically conductive paths defined by two longitudinally extending mutually insulated outer peripheral portions of the supporting rod (16) serving as power rails.
