Hallway and landing light uncertainty

[Kainroberts13]

Hi all,

I have tried to change my hallway and landing light switches, both metal front plates. I cannot seem to figure it out. The backplate has an l1, l12, l21,l22 and 2 common.

In this case none of the incoming 3 sets of cables are labelled, (below is a picture of the wires.

Please could anyone point me in the right directions, thanks.

No picture. Just copy and paste.

Huh? It’s a genuine question. To my knowledge I attached a picture

This is the picture

Firstly - the switches are two triangles; not top and bottom.

I would think the black wire should go in with the blue as indicated but first
make sure the Red, Blue and Yellow from the same cable go to the same switch.

Is your picture of the new switch ? It must be earthed,and it isn't !

The backbox is earthed - won’t that earth the switch when it’s screwed into place?

 

[EFLImpudence]

It might - or might not. The switch itself must be earthed.

It certainly wouldn't be earthed when the screws are removed,nevertheless the switch plate MUST be earthed.

I would assume either black centre right, or red top left is wrong. Either the black should be centre left, or red bottom right.

But which is wrong can't tell.

Show us the photo you took of the original switch before starting.

Don't rub it in!

Presumably the picture is of the old switch??

And you haven't started to fit the new switch yet?

Good. That's a relief.

Before you disconnect the old switch, can you send another photo, showing which WIRE emerges from which CABLE, please.

We'll have this done in no time.
