Automatic Reset: A thermostat that automatically resets to its pre-trip contact configuration at a factory preset temperature.
Bimetal: Two metals with different rates of expansion molecularly bonded together to form a blade or disc for a thermostat.
Differential: (also known as Hysterisis) Refers to the difference between the opening and closing temperatures of a thermostat.
Maximum Temperature: (TM or Tm) In reference to a thermal cutoff, the maximum temperature to which the device can be subjected for a period of ten minutes without resuming conductivity once it has opened.
Minimum Differential: (also known as deadband) The minimum number of degrees between the actual open and actual close temperatures.
Normally Closed: Contacts open on temperature rise.
Normally Open: Contacts close on temperature rise.
S.P.D.T. (Single Pole/Double Throw): A three terminal switch possessing both Normally Open and a Normally Closed contact configuration.
S.P.S.T. (Single Pole/Single Throw): A switch with a single set of terminals and a single set of contacts.
Snap Action Thermostat: A thermostat with a Bimetal element that snaps to close the contacts when the activation condition is experienced. This construction permits the clean break of loads.
Thermal Cutoff: A thermal cutoff is an electrical safety device that interrupts electric current when heated to a specific temperature.
Tolerance: The allowable range above and below a nominal temperature.
