I cant see otherwise how a metal faceplate could be leaking 10ma.
If that was really the case then 3 of them would trip an RCD.
You could just change the switches to normal types with no metal front plates.
This would get you out of trouble.

They'll only leak 10mA if they're actually connected to earth, not just sitting there, so they won't trip an RCD.

But as you ask, where is the leak to the faceplate coming from? If it's still there with the switch hanging from its wires then it's just the switch and the plastic replacement will sort it. If it's not, it must be coming from the backbox which is an altogether dodgier state of affairs.
