As a late addition, I added a neon pilot light to indicate when the saw has power. It turns out the "slow start" feature of the motor controller is very slow: when starting the saw for a slow cutting speed, it can take almost 5 seconds for the blade to start moving at all. It's a little disturbing, since it feels like flipping the switch didn't do anything, The pilot light is good feedback that the switch actually did something.

The pilot light isn't wired directly to the switch -- it's connected at the power inputs to the motor controller, so it will reflect power being interrupted by the circuit breaker or the motor's thermal cutout.
