The present control is based on a Schichtwider » standj in which one applied to an isoxygen pad Resistance layer with one hand of the insulating material under- » location provided metal layer is electrically connected.

With such resistors, a higher ohmic value is achieved.-Da- = · through, d &ö's the resistance layer and the. Metal layer can be removed by suitable measures ₉ so that .a-.S ,. Meander-shaped © resistance patterns are created. "_..
