Intermediate switching in conduit tube

[domestic spark]

Can somebody send me some wiring diagrams please, I understand t&e method but getting confused with singles method. I have 4 lights. Very bottom light is just 2way. So 1g1w switch down stairs. First landing, 2g2w switch. So I need 3lights to be controlled by intermediate switching. Intermediate will have to be on the top floor because of the way the tubes run.

I cannot remember where I got this from, it may have even come from this forum, so thanks to whoever put it on the net.

Here's two ways that depend on where you feed the system from

If you have worked out where the intermediate switch has to go surely you know the answer to the question you are asking

Why does the intermediate have to be at the top? Surely that will mean more cables and will they all fit in the tubes. How many floors/lights do you have

Maybe I'm not understanding your description

Sorry to add to your confusion but Imm guessing...stairwell...?

If so what about running man and emergency lighting...?

At a company I worked for years ago a few of us found numerous different ways to first fix two way and two way and intermediate circuits and then work it so the guy who hated two way circuits got to do second fix on them always good for a laugh

I remembered the make.
Eurolite.co.uk use crabtree switches, and will put 2way and intermediate switches on the same faceplate. I don't know If they do white plastic.

You can if you want, use an intermediate as a two way. So a two gang intermediate will do.

I have done this before Tony, on a hospital contract, long corridors and a mix of 1W, 2W and intermediates, the firm I was contracted to only supplied intermediate switches, this was to rationalise stock, and I suspect to get bulk discounts, as the intermediates could be used for any of the others.

That’s it!
Replace all light switches with intermediates.

Confuse the hell out of DIYers and the Electrical Trainee’s!
