Thought I just had
Did you, so why is my one wrong.
Mine is right and so is PBod one right
I will give you a clue, only one has the live in L1, the other dont even have an L1

Your old school like me, your not a lot of help, do you use MK much

Why do consider it the standard method when clearly there is no standard or even loose convention?
Why do you consider it good practice especially? And why would you consider it not such good practice to do it the other way?
Fair enough, still waiting for the MI diagram though
Isnt this what started it, he feels its in the MI, I just showed it my way he has yet to show me wrong, even though I agree it is irrevalant I have my way of doing it and how I was always taught and confirmed by MK at the time, may I ask paul have you been in the trade over ten years

I'm not in the electrical trade as such, but I've certainly been involved with all things electrical and electronic for a lot more than 10 years.

Thanks, I wasn't absolutely certain which two we were comparing at this moment. So one MK diagram shows the 1-way with C & L1 connected one way round, and the other shows them the opposite way round (plus there's the note on one I mentioned earlier about terminals may differ).
So really MK is pretty much saying it doesn't matter either.

I don't think any one is saying any one is wrong, but we are going around in circles and indeed the popcorn has run dry.
I consider it good practice to use the Com term as permanent live on one way switches. I know it works the other way and we can most probably all find documents to support our personal methods of doing things.
I have posted an instruction guide issued by MK with one of their one way switches.
It shows a simple one way switching diagram with mains feed to com and term 1 to load, the switch in question just so happened to be marked up on that switch as Com and L1.
This is how I was taught to terminate one way switches up and this is what I thought before this thread started, was common practice to keep switching arrangement consistent and I can't remember every browsing over the MIs issued with these type of accessories ever contradicting it.

Ok thats good,
As You may well know the switches marked L1, L2, com were not only marketed as for two way but also as change over switches, in that mode there could be Two live inputs and as you also know a "common output.
As well as the various ways of connecting as Two way use some needing the feed into "Common".
However the drawing i show is 8 years old and all drawings of that era showed Live into L1 Or L2 for one way wiring and was consistent although as you say it was widely ignored, for ease of connection, etc and mainly because it never mattered.
Recently Mk acknowledged this and decided to remove the L which was associated with the symbol for Live on there switches and rather than using L1, L2,L3 like some did, they opted for Com, 1, 2, therefore no terminal was labeled as L for Live.
Pbod drawings are current and are not marked L and as shown the live is connected to the "common"

The old one has the live in L1
The latest one is not labeled "L" and indeed has the Live in common

So back to the same sort of markings as some of the older switches which were marked Com, 1W, and 2W. As both 1-way and 2-way single-pole switches in basic lighting applications should always be in the live side of the supply anyway, it can be taken as read that all (two or three) terminals are live, or can be live with the switch in the appropriate position.
