Fair enough, albeit it's hard to see why they've bothered to put that earth strap (between the screw holes) if there's no metal involved.plastic
Whatever, if that's the case, you could just connect the earths to the backbox (if metal). It's hard to see what useful function a flylead would serve, but it would do no harm to fit one. If the backbox is plastic, then just connect the earths that earth terminal on the switch.
