Two lights one on one off

[Andrewhoddie]

hi

I have two outside lights that come into the inside switch with one cable. Following some decoration work where I think the light switch plate was removed to decorate I now have an issue with the lights.

With the light switched on - one outside light is on and the other off, if I switch the light off the other light comes on and the one that was on turns off.

I have checked the wires and all seem in place and as before. Does anyone have any idea how this could be resolved?

Thanks
Andrew

Turn off the power at the fusebox/consumer unit, open up the switch and show us some pictures of the wires.

Check the photo you took before you took the switch off with what you have now.

I have two outside lights that come into the inside switch with one cable.

That can't be correct.


Edit -I suppose it could be - with 4 core or more - but a bit odd.

That can't be correct.

Why not? How about a triple and earth cable, neutral and two switched lives.

I would imagine a fault such as this where the two switched lives are connected to L1 and L2 of a two way switch.

Did you see my edit?

No. It had not been done when I replied.

Hi here are the photos as requested, one set of wires is for the outside lights and one for the inside lights (they are working correctly). Thanks

 

[rsgaz]

Is there another switch that also does the outside lights?

 

[Andrewhoddie]

Hi

This switch does the outside lights and the inside light, I’m not aware of another switch, and it was working prior to the decorating.

Thanks

I’m not aware of another switch

OK. In which case, if this jogs your memory, were the blue and yellow wires actually in the same terminal/hole together? (only for the outside light switch, not the inside one)

 

[Andrewhoddie]

Sorry I can’t remember as I didn’t do the decorating, when I unscrewed the face plate the blue wire was loose so possibly, but unsure

 

[rsgaz]

Put the blue in with the yellow. Turn the power back on and see if it works correctly now.

 

[Andrewhoddie]

Thanks soo much now working correctly

Next time take that photograph first.
