This conical spring is used as an electrical contact in the LED lighting industry.  Design and Manufacturing Challenges included controlling the large end diameter so that the spring properly installed to the mating base plate, controlling the taper of the body so that the body coils completely nest and allow the spring to compress to a minimum solid height, maintain minimum free length variation to control load at length within a narrow tolerance and maintain minimum 10,000 cycle fatigue life without failure.
