ABSTRACT:
Electrical devices comprising a layer of a PTC conductive polymer and a sheet electrode in contact with each face of the PTC layer. The electrodes extend to the sides of the layer and the sides of the layer are concave, and this results in improved performance. Preferred devices are circuit control devices which protect a circuit from increases in current resulting from a fault.
