Abstract

A Resistor bank has first and second supporting member. Held on to the supporting members is a resistor element comprising a strip of resistor material which is bent into a zigzag shape. The strip is continuous and has a non-planar cross section profile. A plurality of insulating spacers mounted end to end on each of the first and second supporting members isolate the element from the first and second supporting members. The engaging surfaces of adjacent spacers are of a complimentary shape thereby to enable each spacer to move relative to each adjacent spacer with any flexing of the relevant one of the supporting members. The element is held by a plurality of clips each at a bend thereof on to a respective one of the supporting members. Each clip has at least one fastening lug for insertion into at least one fastening hole in a corresponding bend in the element.
