Bimetal disc thermostats are thermally actuated switches. When the bimetal disc is exposed to its predetermined calibration temperature, it snaps and either opens or closes a set of contacts. This breaks or completes the electrical circuit that has been applied to the thermostat.

There are three basic types of thermostat switch actions:

• Automatic Reset: 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.

• Manual Reset: This type of control is available only with electrical contacts that open as the temperature increases. The contacts may be reset by manually pushing on the reset button after the control has cooled below the open temperature calibration.

• Single Operation: This type of control is available only with electrical contacts that open as the temperature increases. Once the electrical contacts have opened, they will not automatically reclose unless the ambient that the disc senses drops to a temperature well below room temperature.

Features/Benefits

* Offered in a broad temperature range to cover most heating applications
* Auto and manual reset
* UL® TUV CEC recognized

Testing Process

Test method of action temperature: install the product on the test board, put it in the incubator, first set the temperature at -1°C, when the temperature of the incubator reaches - 1°C, keep it for 3 minutes, and then cool down by 1°C every 2 minutes and test the recovery temperature of the single product. At this time, the current through the terminal is below 100mA. When the product is turned on, set the temperature of the incubator at 2°C. When the temperature of the incubator reaches 2 ° C, keep it for 3 minutes, and then increase the temperature by 1°C every 2 minutes to test the disconnection temperature of the product.
