    Warning....DIY Novice alert

    I decided to replace a broken faceplate light switch as the rocker itself was broken.
    I isolate the power, removed the faceplate and made a note of the 2 pairs of cables running to Com 1, nothing in Com 2.

    Edit: Red a Yellow pair in the top Com1 and Red/Red in the bottom Com1

    Replaced and tightened the screws, switched the power back on and nothing......coincidentally or not the extractor fan, powered by the same switch also stopped working a while back.

    What have I done wrong?

    Are you sure that you have put the cables back as they were , a different switch may have the commons in a different place .....

    Doesn't make a lot of sense.

    Is it a double switch to have a Com2?

    Did the extractor come on with the light or have it's own switch?

    There can't be two Com1s as you've posted. A pic would be a good idea.

    Although if it's only a single switch then faulty switch aside, the only mistake you could have made is wiring to terminal L1 & L2 with nothing in the common. That's assuming you kept the wires in their original pairs. A single switch should have one pair in the common & one pair in either L1 or L2 depending on which way you want on/off to be.

    I'll take pics tomorrow and upload here....There is only one switch that controls the light and extractor fan, I guess I used the wrong terminology, sorry.

    There is 1 x Com and 1 x Com 2, not as I originally posted

    Again, there should only be one common (Com). The other connections are always labelled L1 & L2. With the switch in one position the common will be connected to L1 & in the other L2. So as long as you have one pair in the common it will work, it just may work upside down until you get the right L connection.
