Light switch wiring two way

[spyder53]

Hi I'm fitting metal light switches through out house Inc kitchen I've removed switch cover and found that the back box is plastic without an earth is it possible to take earthwire direct to back of switch? If not how can this be done

Yes take the earth directly to the switch plate

If the switches are metal they will have an earth terminal.

If you have a metal box most people consider it good practice to also connect the earth terminal on that to the switch one.

I take it you do have earth cores in the cables?

yes I'm aware the metal switches have a earth post prob is the back box is plastic with no earth post the existing cable do's have an earth

 

[ricicle]

Yes take the earth directly to the switch plate

Ok sounds the best do you know if this a recognised practice as I'm starting in the kitchen and do not want any nasty shocks if you know what i mean

If the back box is plastic then there is no requirement to earth it. On the other hand a metallic switch plate must be earthed.
