2 Way switch Pleading for my sanity

Hi guys, having read some of the posts and seeing how helpful you lot have been I'm hoping for some help and hoping I'm missing something stupid.

I attached a drawing of what i'm challenged with.

This light setup is on the landing and works fine on a single switch upstairs but I wanted to add a switch downstairs to create 2 way.

I looked at the wiring diagrams and watched the videos, changing the wires in the first switch and ran the 3 core and earth between the 2 switches, nothing! the switches are doing nothing despite power running through them. I ve also tried the 2 cable and com in and out method and that didnt work.

Like ive said works fine on a single switch, I've run a contuinity test on the cable I ran and also tried this with a metre long cable with both switches at the point of the first switch.

brand new mkswitches all new cable and LED's. Also the Wago xl will have another 4 lights and switches run from it eventually thats why it exists

Last thought is its a faulty switch some how but im pulling my hair out now.

Please help.

Many an hour wasted by faulty new parts.


The switches appear wired correctly but I don't understand the ceiling arrangement.

This all it needs - earths all connected together of course.

Thanks EFL. Surprisingly both the MK the switches were faulty picked up 2 new ones this morning and worked first time.

I will therfore playing the lottery this weekend as buying 2 and getting both faulty has to be some kind of sign, just wish I knew what the actual issue inside them was but hey ho, we can see the light!

Just a thought, did you at any time during this process blow a fuse or trip an MCB?

I didn't the guy at my wholesaler was intrigued to say the least and took the switches apart only to find "half a mechanism" and put it down to bad manufacturing. He reported the batch so maybe a run of dodgy switches.

I'm not hugely surprised.... I ordered a MK 2-gang 2 way switch from TLC, and 1 of the gangs the L2 didn't function. Wen't to B&Q and got another, exactly the same issue!!

3rd time lucky.....!
