Using the principle of differential expansion of metals, a temperature increase causes the stainless steel outer case to expand at a greater rate than the internal bridge assembly. Because the case is in direct contact with the heated surface, a temperature change is sensed almost instantaneously. With an increase in temperature the case expands resulting in a linear change of the internal bridge assembly causing the electrical contacts to open. This turns off the heaters. A decrease in temperature closes the contacts, restoring power to the heaters and turning them on again.
