I have a problem with trying to re-wire a 2 gang, 2 way light switch that operates the light at the bottom of the stairs and the light at the top.
I can get the light at the top to work, but for some reason, not the one at the bottom.
I have two sets of cables leading to the switch. One cable has a red and black wire and the other set has one red, one blue and one yellow.
For the cable that has the red and black wires, i have wired the red into the common position and the black into the L1 position on the one switch (leaving the other L2 position free) and this works the upstairs light ok, but i am not now sure about the other 3 wires (i have tried various configurations, but to no avail).
Can anyone point me in the right direction???
