Adding a 1g 2w switch, plz could u check my diagrams!!??

Hi there!

This is my first post, looks like a good forum, plenty of useful info.

I am wanting to add a 1g 2 way switch to a 3g 2w switch, as the middle switch on the 3g switch which leads to the light in the conservatory is currently just used as 1w, but we've made the conservatory bigger and have an extra doorway going in from the kitchen so could do with a light switch there aswell as the existing one is by the other door in the hallway (the 3g 2w switch).
I'm used to the basic principles of electrics (learnt a bit from my old boy over the years, but alas he is no longer with us to rely on)
I think I have got the method right but would hugley appreciate if someone in the know to could check over my diagrams to confirm and/or correct?
I've had a browse at the Electric info sticky's which are good, the only difference I have really is that the mains cable and cable to the light has been added when the old conservatory was first put up.

Here what I'm thinking: (all on the middle switch on the existing 3g, using 1mm 3 core & earth to link the existing and new switch)

- Move the Red L which is currently in Common to L2
- Leave the wire to the light in L1
- Then Com to Com, L2 to L2 and L1 to L1 and connect earth's
- Leave the two Black N's terminated in the terminal block

Here is a pic of the 3g switch (bit hard to see all the wires form the angle)

So here is a diagram of how it wired:

And here is a diagram of how I'm thinking of wiring it:

Thanks in advance for any help!!

After a cursory glance, the diagram you provide for the existing wiring makes sense, as does the one for the proposed new wiring with additional switch.

Nice 1 folks,

thanks for the quick replies.

Great drawings as well, what software did you use.

Thanks!
Just used the Microsoft Paint that comes as standard on Vista.
I do usually you Adobe (Photoshop C2 etc) but have just got a new PC and haven't installed all programs yet.

Thanks again,
I will get on with the job in the morning.

LOL! Yes, well since Windows 1.0 first come out in '85! (It was on my very first IBM!!)

(when did it cease being called paintbrush? 95?)

And yes, exaclty, '95! In fact it was only called Paintbrush from Windows 3.0 (1990) thru to Windows 95, when it changed to just Paint and was the same prog thru to XP and I notice it has some slight changes in Vista (zoom and crop) but I've not used it for years! Remember kids, only use Paint if you really have too!
Think were inthe wrong forum here, how did we get onto tech-nerd stuff!!??

Meanwhile, back at the ranch, got the leccy job done and all is tickety boo!

Thanks for your inputs.
