An electrical contact fixture is positionable on a surface and is connectable to the surface near a central portion. An electrically conducting continuous band extends around the central portion parallel to the surface. The band and the surface are connected by springs so that the band can be moved parallel to the surface when the fixture is connected to the surface. The fixtures can be stacked one upon the other and insulated from each other to provide terminals for electric currents and spaced at various distances from the surface. A collector has a resilient, elongate, serpentine portion for extending parallel to the surface. At least one collector contact is located along the serpentine portion. The collector contacts are in spaced-apart parallel relationship along the serpentine portion.
