Wiring a dimmer switch....
Hope i'm doing this right.....
i'm trying to wire up a dimmer switch (not too difficult I guess) but my problem is this..... Both the wires on the existing light switch are red so how can I tell which one is 'live'?? The connections on the current switch are marked L1 and Com (i think), but this doesn't help me??? I'm sure it's a simple answer - but i'm not electrically minded. Your assistance is greatly appreciated. Many thanks. |

It would matter if it were a 2way switch and there were three or more wires. It would also matter if something else was different, but it wasn't\isn't, so doesn't matter No it wouldn't. Of course it would. If the wires became mixed up the switch would not work correctly. Yes, if it was a two way, but it's not, so it bears no relevance to this thread. Also, there are at least two ways to wire a 2 way light circuit. There's more than one way to skin a rabbit, your point is? SJW A.C.S. Ltd. |

I think you could be getting confused with something else, or making it up. ;-) I'm not confused... Ignoring the picture of the U.S. switch with wire nuts, for a 2 way lighting connection in the UK, the placement of wires certainly matters. I know the placement of wires matters in 2 way switches, if I were to take off my shoes and socks I would be barefoot. What relevance has any of this got to a 1 way dimmer with 2 red wires and 2 terminals on a 1 way switch? Although if both the feed and switch wire in the twin from the fitting are red then none of them go in common, they go in L1 and L2, any way round, doesn't matter. SJW A.C.S. Ltd.

Yes, if it was a two way, but it's not, so it bears no relevance to this thread. Yes it does relate to this thread - you replied to this message by Andy Hall: " If it's only a one way switch, as this is, then it doesn't matter. It would matter if it were a 2way switch and there were three or more wires." The poster was correct in saying in this situation, for a 1 way switch, it didn't matter each wire went where. He also pointed out (just so the poster didn't assume it was also the case for more ways) that had it been a 2 way switch then it would have mattered where the wires went. Your reply to that (in other branch of thread - not that included at the top of this message) was: If it's only a one way switch, as this is, then it doesn't matter. It would matter if it were a 2way switch and there were three or more wires. No it wouldn't. SJW Which is an incorrect statement - especially as you then said later: "I know the placement of wires matters in 2 way switches". The only thing I can see is that you were being troll-like in making a vague confusing reply of "No it wouldn't" meaning it didn't matter because it wasn't a 2 way switch (which was also what the poster said) - but knowing that it would be mis-understood to mean that the wiring didn't matter on 2 way switches. This replying then went on giving obtuse replies - not clearing it up early by saying "It doesn't matter in this situation because its a 1 way switch". That, to me, is troll-like behaviour. David |

I was simply providing a small piece of additional information, so
that the OP, who was uncertain about which way wires go in a 1 way switch, would be prompted to investigate further should he work on a 2 way switch in the future. If somebody changes one switch, then they may be planning to change another. I didn't provide complete information on how to wire a 2 way switch because that was not necessary. 1. Mentioning 2 way was totally unneccesary, that's kind of what I was getting at. 2. If you're going to bring it up explain fully, half a story confuses people more than it helps. 3. I haven't a clue what you're on about anyway, I'm losing the will to live. SJW A.C.S. Ltd. |

Your reply to that (in other branch of thread - not that included at the top

If everyone would have just left it as my original answer, which was simple as the OP wanted it wouldn't matter. When people keep sticking irrellevant posts in threads it just confuses someone who doesn't know, which generally the OP wouldn't. If they wanted to know about two way switches they would ask about two way switches, or buy a book. SJW A.C.S. Ltd. |

Wiring a dimmer switch....
I'm afraid i'm a typical woman.... Wired one of these things on before, and
got a shock, hence my hesitation... Some nice bloke at B&Q told me how to do it before, but i've forgotten..... Got a feeling he said that whatever wire is currently in the Com terminal should go to the 'live' terminal on the new switch, but can't honestly remember. One good thing is.... I now know how this newgroup works - well, sort of! Wish me luck, will try and wire switch on tomorrow. Thanks for all the assistance received............ watch out for my next problem :-0 "Dave Plowman" wrote in message ...

Actually, what I meant was if it were a two way switch with a twin
coming from the light fitting it wouldn't matter which way round the live and switch wire went into the two terminals that they were required to go into, (L1 and L2, or similar). If everyone would have just left it as my original answer, which was simple as the OP wanted it wouldn't matter.

Andy's post was perfectly clear (as is his wont), a small additional amount of information that may have saved the Op (or someone else reading the thread) a small amount of heart ache if they came across one that was 2 way switched. When people keep sticking irrellevant posts in threads it just confuses someone who doesn't know, which generally the OP wouldn't. What then confused the matter was your reply to Andy and the ensuing thread. -- Chris French, Leeds |

That's why the OP is confused, because of the simplistic, non-specific advice from Mr DIY shop. ;-) Doesn't matter anyway, I posted the answer that solves the problem months ago. SJW A.C.S. Ltd. |
