Marc Oconnell · Answer 2

The NEC requires the use of a metallic faceplate for this situation.

Explanation:

NEC 404.9 (B) requires a metal faceplate having a means for grounding to be used in older installations where there is no ground for an equipment in a metal box switch located within a conductive floor. There is however an exception which states that as long as the wiring method does not have anything to do with an equipment-grounding conductor, it is required that a snap switch that is wired and located within reach of conductive floors must have a nonmetal faceplate or protected by an interrupter.
