If the installation is designed using plastic switches and an earthing terminal hasn't been provided on either the backbox or switchplate does that mean an earth shouldn't be taken to the switch at all? If manufacturers aren't providing us with earth terminals anymore maybe they're telling us they want us to revert to the old style method of not taking earths to switches.
What happens when the householder goes to B&Q and replaces said switch with a nice metal one?
