Abstract

Abstract A device for supplying an electric receiver whose position is variable on a surface, comprises, on said surface, a network of parallel strips made of an electrically conducting material, of the same width and spaced apart from one another, these strips being imbricated alternately in one another. These strips form two assemblies respectively connected to the two poles of a source of electrical current. A current pick-up with variable position bears at least two sensors adapted to come into contact with the conducting strips, and connected to a switching circuit for supplying the receiver. The network of parallel conducting strips is covered with a layer of insulating material and the current sensors are made in the form of metal contact styluses of the same length passing through the layer of insulating material forming the upper covering applied on the conducting strips.
