Connect the thermal switch output so that the main circuit power supply is
shut OFF when the contacts open.
When using multiple External Regeneration Resistors, connect each
thermal switch in series.
The resistor may be damaged by burning, or cause fire if it is used without
setting up a power supply shutoff sequence using the output from the
thermal switch.
