Mechanical Thermostats are designed to keep components safe in situations where there is an excessive amount of temperature. Components in this family will open or close a circuit that they are installed in when the Switching temperature (Adjustable, 14°F to 500°F) of the device is exceeded. The Reset temperature ranges are Manual Reset, One Shot, and 20°F to 440°F with Current ratings of 0.045 A to 25 A.
