i want to change a double light swith, the existing switch has two red wires at the top. a red wire is connected to the bottom i'm assuming L1 or L2 and then a brown wire (one end connected in with the red and the other end connected on its own in the hole next.
the switch i have to replace it with has L1 and L2 top and bottom, do i just copy the wiring on the switch that i want to replace?
