I need to put 40mm switch in a 30mm box

[ikearns]

Am upgrading a few light switches around the house but the new switches are deeper than some of the boxes that are in situ.

For the surface mounted boxes then thats not a problem (just get a deeper box) but the those which are sunken into the wall is an issue cause I cant knock any more of the wall out to make them deeper.

Is there anything that you can get like a collar which adds depth to the box to take a deeper switch. Havent found anything on Screwfix

Cheers

Cause I would make a complete hash of it. A couple of them are in a plastered wall and if I were to replace the box then I could balls up the plastered wall.

Thanks for the link, that looks ideal for what I am after.

Fair enough!

Just make sure you check your new switches first. Some accessories have square corners...

and some have radiused corners...

The extension collar needs to match or it'll look awful.

You'll get better with practice.

A couple of them are in a plastered wall and if I were to replace the box then I could balls up the plastered wall.

And then you can fix the little bit of plaster you damage.

But you're making existing holes deeper - you won't be attacking the actual plaster....

Crabtree accessories tend to have more out front and so don't need too deep a back box.
