Thanks

L1 (with com written above/below it) = Com
L2 = L1
L3 = L2

Old switch to new switch...

Daz - why haven't you got a multimeter?

Daz, on your old switch, you will see a diagonal line that separates the two switches.

Turn one side upside down in your head and you will see you have two triangles of terminals - just like on your new switch.

Just copy the connections.

The terminals are labelled differently, but they do the same. Just a quirk of different manufacturers.

And, as well as turning off the power before you start, do not disconnect any other cables that may be in the switchbox.

You'll be looking at a very tricky problem if you disconnect them and forget where they go!

Very important: Your new switch seems to be made of metal. If so there will be an earth terminal on the back of the switch. It is vital that this terminal is connected to the earth conductors using green/yellow sleeved wire/

He's doing electrical work - it's as essential as screwdrivers.

I laid some paving slabs last week. I havent got a cement mixer.

Where the link is on the old switch, move them over to the new commons on the new switch.

Then you move the L2 from the old switch to the new L1 switch.
Then you move the L3 cables from the old switch to the L2 on the new switch.

Make sure the circuit has been isolated prior to changing anything.

I laid some paving slabs last week. I havent got a cement mixer.

1) Multimeters are small and cheap, cement mixers are large and expensive.

2) People tend to change/add electrical accessories much more frequently than they lay paving slabs.

3) You can make mortar by hand - hand crafting an alternative to a multimeter is more complicated, and just not worth it given (1).

So that he could work out for himself which terminal was which by checking continuity between them with the rockers in different positions.

He is replacing a like for like switch, why would he need a multimeter?

And to test if the earth (cpc) conductors are really connected to earth.

No - it was a genuine question - why does he not have a multimeter?

One can be unhelpful and obstructive by not giving people information, or by giving them false information, but how does asking a question do that?

Particularly as the OP's question had already been fully answered would you please provide a rational and logical explanation of why you believe that it was unhelpful and obstructive for me to have asked that?

You made the accusation - you must be able to present a reasoned argument in favour of it.
