When the internal temperature reaches near 120˚C, the
thermal switch opens to cut off the power to the power
circuit.
The thermal switch can be reset itself automatically
when the internal temperature becomes normal.
When the internal temperature reaches near 80˚C, the
thermal switch returns automatically.
