Replacing a lightswitch

[gam3r]

So, I decided to replace a few light switches in my house with newer ones which are basically brushed aluminium. The current ones are plastic and when I went to open one up to replace I noticed there was only two wires(black and red) and no earthing wire.

I've read on the slip that came with the switches that they must be earthed as they are metal based - and also the same on the net.

My question is, what can I do from here if I don't have this earthing wire?

Thanks for all the replies.

Just buy faceplates where the metal facia is totally insulated. I have an old house without earths to switches, and found some lovely metal "screwless" digital touch control faceplates where the metal face clips over the plastic body - totally safe.

Digitals are also much better as you can have 2-way dimming (mine actually allow up to 8-way dimming!).

My switch has plastic surrounding it, but it still explicitly states that it should be earthed:

I'll take a pic of the wiring behind the switch later. I think there may have been a copper wire(not in any sheathing or anything in one of the switches)
(Sorry for the carp pics)
