Light switch wires

[Bonita]

Can anyone tell me how to wire a 2 gang 2 way light switch using these wires? I stupidly removed old switch without looking where wires go. I’ve attached photo of the back of the switch I want to fit can anyone help at all? That would be great. Thanks.

Wow.

shame you didn’t take any photos before you took it apart.

where in your home is it ?

What are the terminal IDs I can see L1 and L2. I assume they are both two way switches. This is probably pretty straightforward.

At a Guess.
the two cables on left go to one switch, you need to look at the reciprocal switch and duplicate the red, blue and yellow in L1, 2 and 3 and the two reds in the other cable go across L1 and L2. The right hand cable again go into L1, 2 and 3 but you need to check the order in the reciprocal switch. You wont blow a fuse if you get it wrong. Make sure you turn the power off when working on it.

you might not blow a fuse but you might well trip a rcd or 2

Hi it’s L1 them com L2 is at the bottom same on the other side.

the landing and hallway lights

Assuming those left cables are paired correctly.
The right cable, red to Com, blue to L1 and yellow to L2 of the right switch.
Exactly the same with the left cable red, yellow and blue at the left switch but also connect the red pair cable across L1 and L2, doesn't matter which way around.
See if that works.

look in the other switch downstairs (ideally without taking all the wires out), needs to be wired basically the same. just make sure you get the 2 3c&e the right way

Seriously, find a local electrician who can call in on his way to or from another job, you will get it sorted for 1 hours labour.

It could take days or weeks suggesting things to try. You really need some test gear and some knowledge, otherwise anything is a best guess and may or may not work.

I say it again for others, take a photo and draw a diagram of how it is wired before you take the old switch off. but of course nobody reads a forum until they have messed up and need help so I am wasting my time.

Facts are this:-

1/ There are NO specific rules for which colours are used in a 2-way switching arrangement.

2/ The actual colours used can depend upon the personal preferences of the person who did the original instalation.. as these are ALL live or switched live functions with NO need for any neutral conductors..

3/ Random DIY guessing could take hours/days to get right..

4/ A competent person with appropriate test gear should be able to suss this out within a 1hour call-out charge..
(or worst case 2 hour call-out!!!!)

5/ I would be opting for the "Pro-Dave" suggestion to find a local electrician!!!!

And the switch markings and terminal locations vary too

In my opinion you have a 2 way switching for the landing and the same for the hall light not something most sparks do, normally it’s just a 2 way for the landing. So power off remove hall switch from the wall it’s probably a 2 gang switch now note the position of the 3 core cable in the switch you have, common or C, L1, L2, you need to mirror these positions upstairs at the switch, now that just leaves the red/red cable upstairs that cable spans an L1 L2 and fits in with the existing cables, so if you have used yellow and red in L1 L2 you’ll end up with a yellow and a red in one terminal and red red in the other
Good luck with that
