Claim:
1. A method of manufacturing an electrically conductive extension/compression spring comprising the steps of: a) providing a cylinder of electrically conductive material having first and second end walls; b) machining said cylinder into separate first and second coils each having coil turns extending between respective first and second ends; c) providing first and second electrical insulating components; and d) connecting said first and second coils to said first and second electrical insulating components with said first coil turns alternating in spaced relation between said second coil turns and said first and second ends of said first coil aligned with said first and second ends of said second coil, respectively, said first electrically insulating component electrically insulating said first ends of said first and second coil, and said second electrically insulation component electrically insulating said second ends of said first and second coils and thereby electrically insulating said first and second coils from each other.
