I wouldn't fool with a thermal switch. Rather, a pressure switch that activates with boost or even a micro switch that activates when you press the throttle more than a given amount.

You can get pressure switches on ebay for pretty cheap. I would look for a Hobbs 76583. Factory set at 4PSI but you can run it up to 7PSI.

Here's another one that would work great. It's adjustable from 2 to 24PSI.
