This type of control can be built to either open or close its electrical contacts as the temperature increases. Once the temperature of the bimetal disc has returned to the specified reset temperature, the contacts will automatically return to their original state.

The 431 series encapsulated 1/2″ automatic reset snap discs are used whenever a moisture or dustproof enclosure is required for safe, sensitive and reliable operation. These thermostats are automatic reset.
