    Hi all I want to change a double light switch which feeds 2 separate lights,the current switch plate has red and black wires connecting to L1 and L 2 on both switches but new switch plate has L1 and L2 and common on each switch... so swapped wires from old switch to new one using L1 and L2 but nothing....any ideas would be greatly received....thanks

    Old switch........L1........L2.....L3
    New swiitch......COM....L1.....L2

    So connect your wires to COM and L1 on the new switch

    It's just two different labelling conventions.

    Or even black to com and red to L1. It does not really matter.

    Intrigued you all say use L1 theres a 50% chance the switches will work upside down, some manufacturers use L2 for one way switching.
    What make switch is it, it should have instructions regarding connecting

    My idea is that in future you should take the trouble to learn how things work before you start to fiddle with them.

    I really don't see why that should be such an outlandish concept.

    And we all should.

    But not by trial-and-error-mistakes if there is a reasonable alternative.

    Unlike, of course, someone who pops up in a thread where he has had zero involvement, just to insult someone.

    Daz - take no notice of GB - he is plumber, and got so bent out of shape when people here started telling him that he was wrong to be charging to do electrical work that they had to lock the thread:

    https://www.diynot.com/diy/threads/2-way-switching-help.493959/#post-4047894

    I guess he's particularly upset with me because I was the first to comment on his blundering, ignorant incompetence.

    the thread got locked because I put a complaint in about you, you moron....
    and so we begin again, you assuming everything the worse about me when you don't even know me....
    lets start with me having 2360 1and 2 16th and update to 17th...2391 gained in 2006 and I am registered with niceic
    but as most of my work is plumbing I grant you...I just needed my memory jogging about a switching arrangement, and for that massive crime I was labelled a scammer and a thief by yourself
