It can be noticed that, in this case, the other needle of each pair of needles is instead in contact with the respective conductor 26a, 26b. The power supply of the lighting devices 100, 100' is therefore always ensured, regardless of their position along the bar 10.
  • the two power supply lines 25, 26 are powered by means of a power supply cable 132 electrically connected thereto at one end of the insulating body 24.
