[QUOTE="poni, post: 546741, member: 1497"] the cable most used in domestic circuits would be Twin and earth ( brown, blue and bare )or three core and earth (brown, black, grey and bare) some times single core and earth( this could brown or blue with a bare core) from your blurry photos it looks like you have one twin and earth and one three core and earth, with the blue of the twin sleeved with brown and the black and grey from the three core both sleeved brown so the twin brown and the blue sleeved brown, should be the switched pair (one permeant live and one switched live ) the three core could be the strappers for the two way switching, 2 of them would be live all the time when switched, so the two way switch has 3 terminals they should have the same cores in each of the switches,( it does not matter as long as all the L1's have the same colour cores in each, and the same with L2 and common , the twin cable has to double up in two terminals, but from you photos its hard to see the numbers on the switches, so I cant tell you which terminals you should put them in , there is no standard switch markings , all makers have there own, all the bare cores must be sleeved with green and yellow sleeving, and joined together and linked the switch plate if it is metal [B][COLOR=rgb(184, 49, 47)]most of all remember the above[/COLOR][/B], its your [COLOR=rgb(209, 72, 65)]life[/COLOR] after all, [/QUOTE]
