(under subclass 315) Subject matter including at least two supporting portions with a resistance element suspended between and supported by these two supporting portions.
(1) Note. Usually the resistance element is rigid and elongated in shape with terminals at the ends with metallic supports receiving the resistor by snap action, or the resistance element is strung between the supports.

290, for a zigzag or sinuous shaped resistor whose element extends through a slot or opening in a supporting frame.
305, for a helical or wound resistor, whose element extends through an opening or groove in a supporting frame. 316, for resistance supports with structure which compensates for or permits resistance expansion and/or contraction.
317, for resistances which thread or project through a support.
