Hi messed up confused. Changing 3 way switch to 2 way switch

MAAZ KHAN · Feb 17, 2018

Hi im a noobie. I tried connecting the electric cable to a 2 way switch from 3 way and it didnt work. I only connected 4 wires. There was 6 wires in total. 3 blue and 3 brown. If i connect a terminal to it will it fix it lol. Meaning if i connect the 3 blues and brown on 1 side of terminal and other to the switch

Hello
1. What exactly is it that you are trying to do
2. If it is just a switch swop, what is that reel of cable for
3. Post a picture of the old wiring before you disconnected anything (you did do this, didn’t you?)

We had spotlights in before and now been removed we have a tube light and them big circle lights. The old wiring was 3 blue in common and the 3 brown in the bottom part think L. Yeh and switch swap from 3 to 2

Your earth wires need sleeving.

Then how do i connect it like which wires go where. There was a 3 switch before. Will i need to use a terminal

MAAZ KHAN · Feb 17, 2018

If i connect that blue to the common and brown to the live 2 way switch. And the 3 brown to the other side of terminal and blue to other side of terminal will it work??

You should not need any more cable! In anycase, that cable is 2.5mm csa and way too big and unwieldy for lighting applications. Normally we use 1.0mm.

The wires to the switch should be in pairs, blue and brown.
First of all, the two wires that used to go to the switch for the downlights. I hope you know which two they were?
Put those two wires in separate bits of the choc block, to insulate them in case they are still live.

Then you'll have two pairs of brown and blue wires. For each pair.
Put brown in the terminal marked COM and its corresponding blue into thje terminal marked L1.

And as noted above, the eartyh wires need sleeveing in yellow and green sleeve and connecting to the earth terminal on the metal back box.
You should not need to do anything else.

It sounds odd the original switch had three cables (six wires) on a three gang switch as this says to me it was three plate and the blues would not have been connected together. If this was done the modern way of bringing the neutral to the switch then three cables is not enough for a three gang switch, the minimum would have been four.
