But its let down by a lack of identification on the conductors.First light switch I have seen on here without a load of copper conductor exposed.
Merci beaucoupTop spot.
Yes it works. But not sure if I should wire up new switches the same?Does it work properly ?
If those are lives looped in the connector, it looks like you're switching neutrals. Get someone qualified to make sure.
It is a good spot because it appears the lines are looped at a block connector with the neutrals to the switch, possibly. Needs addressing.Without sounding silly can you explain this one a bit please if you can?
Definitely as there could be incorrect polarity.Just wondering if I should get a professional in to wire up new switch
I've no intention of sounding silly, but think about it. If you're switching neutral instead of line what's the result......at the lampholder?Without sounding silly can you explain this one a bit please if you can?

Thank you.When you go to change the bulb after turning power off at the light switch you'll still have a live supply there, so there is a risk of electric shock. Not that I would ever recommend sticking fingers into a light fitting regardless.
You need this checked by a spark, as as it won’t take long, get them to check a few more.
How old is the property and / or have you had building work done or a rewrite ?
Good spot Mate, was wondering what those 2 reds are doing in the connector block, so you are more than likely correct in your assumption.If those are lives looped in the connector, it looks like you're switching neutrals. Get someone qualified to make sure.
think it's a good idea, and maybe an inspection of the installation is in order if as has been said, the polarity is incorrect, there could be a few more nasties lurking.Just wondering if I should get a professional in to wire up new switch
..a bit of good thinking, there........after all...well spotted there. but..... has the switch been wired like that after the meter fitting monkey has reversed the polarity at the meter?????????
Thank you.
I suggest you think about it, too......after reading the thread.
Borrowed neutrals is something different. This was common practice in the 70s to take the line supply from one level with the neutrals from another for two way lighting.Is it the term they use for borrowed neutrals
Yes this is possible but I think we need to side with caution in this instance.I think the black in the coman is joined to the 2 reds in conecter as it would of been tight getting 3 cables in the comman although you could of put a red each side and linked and he dint have any red cable left
Bad thinking is that. What's with the two reds in the connector?......look closer, there are three.I think the black in the coman is joined to the 2 reds in conecter as it would of been tight getting 3 cables in the comman although you could of put a red each side and linked and he dint have any red cable left

As well as the two way concern, in a case of properties, many borrowed neutrals occurred when the original CU had only one lighting circuit. A new mcb CU and the circuit being split into two, upstairs and down, resulting in a common neutral. Just bad practice.Is it the term they use for borrowed neutrals
