Abstract (en)
[origin: EP0903713A2] The two-way control switch is fitted at the output of an existing traffic lamp controller (20) supplied from a voltage source (30). The control switch has a current level detector (4) in the cable (2) supplying the principal lamp (22). The current detector controls a switch (6) connected in series with a parallel branch cable (3) supplying a second lamp (23), opening the switch when the principal current is present.
