How to select a thermostat? - Selecting a Thermostat

The three principal factors that influence selection are:
1. Physical dimension and methods of mounting - Full dimensional details are shown under the relevant specification.
2. Medium to be controlled - this may be air, liquid or a platen but whatever the application, a thermostat can be used in temperature control or indicator circuits.
3. Contact action - a thermostat can be selected with contacts to either make or break on rise of temperature.
