Discuss Is this Intermediate switching image from the Student's Guide wrong? in the Electrical Wiring, Theories and Regulations area at ElectriciansForums.net
Ok so on that note, the reason i'm asking is because the GSH electrical channel has a video on this, and he says the L1 L2 from the first switch cannot go L1 L3 and must go L1 L2 on the intermediate switch.Looks correct to me.
but feel free to draw out your solution for comparison

Is he wrong or is that just another way of doing it?
I'm not sure if all intermediate switches are marked L1-L4
AH I see the issue now. Yes. I was looking at the whole circuit which is ok.Guide does appear to be poorly illustrated.
I've seen them with two pairs of L1 and L2 and with A1, A2, B1, B2
I've traced it and it looks like it would operate normally?If wired as per 2nd image the circuit would only ever close with intermediate in one position.
I'm still rather confused as to what you're all saying - so is it the picture of the 'real' switch that is wrong physically, or is it labelled wrong?
The real switch picture and the diagram are laid out the same, so which part is wrong?

It is unconventional for an intermediate switch to work that way but the circuit shown is correct for the wiring diagram of the switch.so is it the picture of the 'real' switch that is wrong physically, or is it labelled wrong?

I get ya i think - so the top left image of how it switches is unconventional? What does it normally look like? I want to learn the common way which is applied to most switches and now feel like i can't really trust the guide i bought.Not all intermediate switches are labelled in the same way, different manufacturers have their own conventions on labelling the same as they do with normal 2 way switches.

I mean i get how it's working in terms of the wiring, but it was GSH's comment here that completely threw me since he makes it sound like a rule.
But would this be the normal way most switches would do it? Is the guide i'm using (IET Students Guide to the Wiring Regs) using an uncommon switching pattern to demonstrate an intermediate switch?The intermediate in the GSH video is shown changing over differently to the one in the first post on this thread,
so his statement is correct for his switch / drawing.

The wiring isn't done like that for the (common) loop in at lamp method. In fact, the student diagram is from wiring that was done a very long time ago.......
You mean GSH's diagrams or the one from the book?The wiring isn't done like that for the (common) loop in at lamp method. In fact, the student diagram is from wiring that was done a very long time ago.......
