    I've got a CLIPSAL intermediate light switch with four blue wires in it. The terminals are not labled except for a small diagram saying 'To 2 way switch' on each pair, how does this relate to my new MEM switch which has L1, L1 on the top and L2, L2 on the bottom?

    Your old switch has 2 terminals at the top, 2 at the bottom.

    Your new switch has 2 terminals at the top, 2 at the bottom.

    They are all lives.

    It matters not which way around you connect, as long as the top blues goes to the top 2, and the bottom blues goes to the bottom 2.

    Out of interest, all 4 blue cores should have brown tape or sleeving on them.

    The old switch terminals are arranged in a circle so they are top + left and bottom + right according to the diagram and they are just blue. the MEM switch has two L1s at the top and two L2s at the bottom.

    OK, forget the switch. Never seen anything like it :eek:

    The 4 blue cores come from 2 cables, yes?

    Put the cores from one cable into the top 2 terminals.

    Put the cores from the other cable into the bottom 2 terminals.

    Its very strange to see tinned copper conductors in blue cable cores. This isn't some sort of control system wiring is it? Tinned copper suggests it is from the 70's, but blue fixed wiring suggests its from after 2006. :confused:

    They are all singles and yes it's from the 60s / 70s, so I'm still no closer to a solution.

    The wiring diagram clearly attached to the side of the switch is the key to your success ;)

    After a bit more digging, I know which two wires come up from the two way switch downstairs, in a normal L1, L1, L2, L2 situation, where would these go?

    So one pair goes to the first L1 and L2 and the other pair goes to the other L1 and L2?
