Hi I've been replacing my white sockets and switches to chrome I've done a few of the double sockets, however when attempting the light switches the switches are earthed to the back box but do I need to do the front plate aswell!? there is a designated earth connection on the front plate but I was hoping I could go with out as the screw connecting the back box should earth it anyway is that correct? I don't really know how I would earth it to be honest. Any help is much appreciated photographs attached are current light switch
