Apologies for the dumb a***e nature of this question to you guys, but my son was doing some decoration and took off a two gang switch (that switches two different light fittings) but did not record where the wires went so he is not sure how to wire it back up. It has two cables coming into the back box, both with blue, yellow, red and earth. Could anyone let me know how to wire this back into the front plate/switches?
Many thanks
