Hi I’m an apprentice looming for a little help understanding some wiring.

Has anyone got a wiring diagram for a 2 gang 2 way switch??
If you are doing loop at switch, how does your feed go to the other side of the switch if that makes sense? Cheers

What cables do you have at the 2G2Way oposition and at the other end of the 2 way system, can you post pics of the cables?

Draw out on a bit of paper three dots in a triangle, two at the bottom one at the top.
Com at the top, L1 at bottom left and L2 at bottom right.
Draw another three dots in a triangle a couple of inches away.
Your two switch wires go to L1 and L2 on the first triangle, your 3core cable then goes com to com, L1 to L1 and L2 to L2 between the two triangles.
That’s it for a standard 2 way switch set up.

Correct, but the OP has stated the loop in and out are at the switch position.

still as spin says, but from switch#1 he'd take a S/L and N to the light instead of Lin +S/L out.

If I've understood correctly there's a two gang switch at each location, each controlling a light. Each light having 2 way control from each location (?). And unswitched L and N available at each switch. I've assumed the lights are near the switches, say top and bottom of stairs. Hope this helps and sorry for the messy diag. Happy for feedback :) .

There are so many ways of arranging the wiring.
Wilko has shown two wire switching for the top light and three wire switching for the bottom light, because this fits the layout required. So the wiring method would be dependent on the location of the switches and the location of the lights.
I have done some similar diagrams, the top left is the basic three wire switching approach and the other two are other possible options for different scenarios. The best idea is to understand how the switching works and then adapt the cabling for your needs.

Richard, great pic. but you have too much time on your hands. get that conduit bender i sold you into work. :D:D:D.
 
If all switches are 2G2W, then Richard Burn's diagrams above all have an unnecessary wire between the two switch locations - in all cases there are two permanent lives running between the two switch locations.
The LH circuit can be achieved with one T&E and one 3&E, while the two RH circuits can be wire with either two 3&E or three T&E between switches.
