Apologies in advance for this very simple question...
I understand that if a dimmer switch plate is metal it must be earthed. I am replacing one plastic dimmer switch plate with another. However, on the inside of the face plate there is a metal plate which the old switch did not have. (Apologies, I can’t figure out how to add a picture)
Does this then need to be earthed? Or is it fine without?
Many thanks for any help in advance.
