This limit switch also functions as a protective mechanism that triggers the stoppage of heating when the temperature set limit is attained. It controls temperature and shuts off the electrical circuit when a particular limit is attained, to avoid excessive heat and related harm to equipment. This is used for high-temperature applications with a set point of 250°F and differential of 20°F.
