Changing switch plate

[NewhouseOldhouse]

Hi

Can anyone advise where the wires go to the new switch plate please?

Old and New ones attached.

Thanks

Wiggly line with arrow = Com.
The others don't matter which way round in this case.
The 2 terminals opposite the Com go to the same switch.
Oh, and earth the metal faceplate!!

If you have LED lamps, make sure they are dimmer compatible.

What does the symbols mean as in com 1, com 2 and wiggly line with arrow etc...

- =
+ =
□=
I =
X =
○ =

For new switch

The dimmers do not look suitable for led lights.
But here is the order for the wires.
Mark the cables and photo them before you remove them from old switch so you can put them back in if new switch does not work.

And make sure new metal face plate will have an earth cable connection to it. If it does not, STOP, and keep the plastic plate.

You can see the words COM on the plastic plate next to your o and your -.


- = COM (wiggly line on switch 1)
+ = L1 (on switch 2)
□= L2 (on switch 2)
I = L1 (on switch 1)
X =L2 (on switch 1)
○ = COM (wiggly line on switch 2)

What terminals were the 3 loose wires connected to before you removed them ?

Grey = O
Red = X
Black =I

For the earth, there is a earth cable connected inside the metal box.

Is there only one copper wire in that green sheath " earth" ??

Never checked that might be 2 wires with earth sheath

Yup, and these wires need to be moved to your new metal switch plate. That is the important place for the earth to be connected to.
Ideally, there should also be a jumper to the backbox, but that isn't strictly necessary!

Tried thie above lights didn't work at all.

Checked the other 2 single gang switches and the red wire is in L1 in one switch and L2 in the other switch. The black wire is the same.

Grey wire is com.

Tried this too lights didn't work.

Any ideas or dimmers will not work?
