:welcomeuhm:

Get yourself a marker pen or similar then mark each wire. one slash for one, 2 slashes for wire 2 etc.

Cores 6 and 7 go to common (marked "B" on the new switch) 4 and 5 to either "E" or "F" (doesn't matter which)

cores 2 and 3 to the other common (Marked as "A" in your pic) core 1 to either "C" or "D" again doesn't matter which.

Lecky off first should go without saying.

Or to put it another way..........

The switch you have is the same as the new switch, but half is upsidedown. (quite normal) and its labelled almost the same.

Your switch has Com, B1 B2

Your new switch has Com 1way 2way

So you need to put what is in Com on the old switch into Com on the new switch
what is in B1 into 1 way

So you need to put what is in Com on the old switch into Com on the new switch
what is in A1 into 1 way

The new switch is two switches side by side. Like !!
The old switch is two switches one upsidedown to the other. Like i!

Left hand switch is same both pictures, right hand switch is reversed top to bottom, however some thing seems wrong.

Right hand switch is wired simple on off, the left hand switch can't see bottom right terminal, I will assume wire 7?

However it would be unusual for the link to go into com on both switches, assuming one is two way and other simple on/off. So I wonder if there is anything wrong with the original switch, or if it is simply wired wrong in the first place?

It seems to be wired as two on/off switches rather than a two way switch.

Thanks for the help guys - can you just confirm the short wire number 3 on the pic still connects common to common on the new switch ie A + B?

Since you say two way I would assume left is two way, so the normal wiring for two way the link would go from com or single way switch to either one way or two way on new switch.
Listing cables required.
Single way switch 2 wires line in and line out.
Two way switch either 5 or 3 wires, if master then 5 if slave then 3.
You can reduce wires by one by borrowing a line from other switch.
So that gives you the 7 cables so far so good.

Now looking more carefully there are only two holes used with both switches, for two way you must use three holes so something wrong.

Put the cork back in, e-m, OP didn't mention two-way switching - I think you were the first to introduce this confusion then compounded it yourself? Both old & new switches seem to be 2-ways used as one-ways, OP queries the terminal arrangement and !!/i! explains it perfectly.

Was e-m the first to mention 2 way switching?

Look at the header of the post.

Point taken, apologies, but...

OP means 2 gang, not 2 way - the picture of his old switch shows only two of the three terminals in use on both gangs.

Yes it will just follow the instructions I gave, mark the individual cores before starting as otherwise you'll be on a hiding to nothing with those core colours.
