2 way switching

soot · 30 Oct 2003

I have a one way light switch which has the supply going in and the feed to the light going out.The supply has the red connected to the common and the black to a terminal block,the feed has red to L1 and black to the terminal block,how do i wire this into a 2 way switch with a link cable that i have running to another 2 way switch.All the diagrams i have seen do not show where the supply is connected.

ps my new switches have L1,L2andL3 on them no common, does that make any difference.

the one at the top will be common.

Install your new switch and connect with 1mm 3 core and earth as follows

Yellow to top C
blue to L1
Red to L2

earth to brass terminal (cover wire in green sleeving)

Origonal switch

see previous (should be the same , along with the existing wires)
