2.1 Intended use
The model TFS35 bimetal temperature switches are used to limit temperatures within a
wide variety of applications.
They monitor the temperature of machinery and equipment and, for example, switch off
machinery if it overheats or switch on a fan to cool the equipment.
Bimetals form the basis of the model TFS35 temperature switches. Temperature sensing is
carried out by a bimetallic disc, which snaps over when the Nominal Switching Temperature
(NST) is reached. On cooling back down to the Reset Switching Temperature (RST), the
switch returns to its original state, so that the monitored equipment can again work normally.
