Im not sure there's much evidence of switching. There are large numbers of people who didn't vote relative to the numbers that separated candidates, so the likely explanation is that people who normally dont vote voted Trump and people who normally would vote Hillary didnt vote. A little bit of those two things would tip it. Which is what we see: high rural turnout; Hillary underperforming/low turnout in urban areas. There's just a group of white people who like Trump, and nobody liked Hillary.
