Hello,
I am trying to understand the wiring done for an already working setup in my home by an electrician: a dual light switch (Legrand branded, if it matters) with only 2 wires connected to the switch. It really puzzles me how the switch can control two separate light fixtures, since there should have been 3 wires instead of just 2 connected to the switch? Can someone please explain? Thanks in advance!
