If the box is "UL Listed", the "little sheet of plastic" qualifies as
the "physical barrier" or "separation" required by NEC.

AC has been know to induce voltages into nearby cable runs.  Usually
this isn't measurable by a standard VOM (I say *usually* - I've never
actually come across an instance).  Most "erratic keypad operation" is
caused by poor connections (or a component failure).
