Abstract
In the illustrative embodiments disclosed, one or more independent current paths are provided in a gas spring by use of printed circuit-type conductors. The printed conductor or conductors are preferably formed on a strip of insulating material using known printed circuit techniques, and the strip is then affixed to the cylinder member of the gas spring by an adhesive or, alternatively, by a heat-shrunken surrounding, plastic tube. A current path may be connected to provide a switch function or to establish a closed circuit over a substantial portion of or the entire stroke of the piston rod member. Where plural current paths are provided, the different paths can be given different functions.
