(under subclass 283) Subject matter wherein the resistive element includes three or more elongated resistive portions which are substantially parallel, alternate adjacent ends of the portions being electrically connected in series by conductive material usually formed as a connecting wire strip or block, thus forming a zigzag or sinuous pattern.
(1) Note. For classification in this subclass the jumper or spacer must be conductive, at least to the extent of having a substantially lower resistivity than the resistive portions. Further, the jumpers or spacers must be distinct from the resistive portions. Where the jumpers or spacers are integral with the resistive portions or of the same material or resistivity, classification is in the generic subclasses 283+. Further, when no jumper or spacer is present, the strips directly contacting each other at their respective ends classification is in subclasses 283+ above.

288, for compound or multiple zigzag resistors one of whose zigzag patterns is formed by jumpers or spacers connecting elongated resistance elements, which are parallel or in parallel planes.
295, for plural resistors generally which form a unitary structure and are connected in series by conductive jumpers or spacers.
