13. A method of manufacturing resistor arrangements comprising the following steps:
-
mechanically and electrically connecting an elongated band made from a resistive material on its longitudinal edges to an elongated band made from an electrically conductive material, separating the bands connected to each other into several resistor arrangements along several perpendicular separating lines, generating in the individual resistor arrangements perpendicular recesses between two adjacent separating lines, wherein the recesses extend from a longitudinal edge of the resistor arrangements starting inwards at least up to the band made from the resistor material in order to form two connection elements separated from each other. - View Dependent Claims (14, 15, 16, 17, 18)
