Based on the differential expansion
of metals principle, an increase in
temperature causes the stainless
steel outer case of the Surface
Mounting THERMOSWITCH®
controller 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.
