What on earth are you trying to acheive? you have got a neutral going from the CU, to two lights and then to a switch??!!

 

[h00tsman]

Forget the CU, that's another junction box/light its coming off.
The PL comes off another light but the 2 lights here are have just live and neutral. Unlike a standard ceiling rose.

Thanks holm. Does it always need to goto Common? Just i've seen a jump from common to L1 on a 2gang 2 way switch.

Hang on, that won't have 2 way? Will make the light permanently live..?

thanks

 

[h00tsman]

Aye yeah. Works, but is that allowed to be done that way?... The common link not supposed to be used always? Does is comply with regs?

What about:

A 4 way junction box would need to be fitted then.

 

[GarethW]

OK then, try...

Thanks Gareth,

Will the second light actually work that way?..

Problem I have are the lights have just L and N, no loop connection...

Holmshaw's way works, but by not linking the commons does that mean it doesn't comply with the wiring regs?

Thanks

 

[GarethW]

Sorry, schoolboy error !

Third time lucky

What makes you think it wouldn't?

 

[h00tsman]

Thanks Gareth, appreciate your help.

Just when i was doing my electrical training they taught us the certain ways to wire 2 and 3 way lighting, didn't know how far you could stray from it.

What on earth are you trying to acheive?

A bl***y great bang when the switch positions are asymmetrical?

What makes you think it wouldn't?

The fact that he doesn't have a clue what switches do?

when i was doing my electrical training

A bl***y great bang when the switch positions are asymmetrical?

I thought this when I first looked at the diagram but doubted myself after the post comments.

Would that be a great bang, or a click and lights go off?

Not has a bang since i was 14 trying to fix a tumble dryer for input, and had leads still set to amps.

I had to break the leads welded to the terminals.
