JUC-31F Series Miniature Thermal Switch is a snap-action thermostat with a bi-metal disc as the temeprature sensing element. Its main working principle is to control the temperature by opening or closing the bi-metal strip. It stays at normally closed/normally open status, it opens/closes when temeprature rising and closes/opens when temperature decreasing. It has the characteristics of snap action,high accuracy, long life cycle, high sensitivity, high reliability, small size, light weight, easy installation. We use international TO220/Y220 standard packingJUC-31F Miniature Thermal Switch has been granted national patent, and has passed UL, TUV, CE, CQC, CB and ROHS. It also has passed the 100,000 life test of UL laboratory. It is widely used in printed circuit board equipment, power supply equipment, audio amplifier, welding equipment, automation equipment and instrumentation for temperature control and temperature protection.

6. Wide application
1 , using the contact temperature installation should be charged with the metal cover up snapping apparatus mounting surface , to ensure that the temperature effect , should be coated with thermal grease or other similar thermal properties of the medium in the surface temperature .
2 , the installation can not cover up the top collapsed , loose or deformed , so as not to affect performance.
3, can not allow the liquid to penetrate the internal temperature may not make the shell cracks , are not free to change the shape of the external terminals.
4 , the product is not greater than 5A current in the circuit , chose the copper cross-section 0 5-1 mm 2 wire connection ; . No greater than 10A current in the circuit , chose the cross-section of 0.75-1.5 mm 2 copper wire connection.
5, the product should be less than 90% relative humidity , ambient temperature is below 40 °C ventilated, clean, dry , non-corrosive gases stored in the warehouse .
KSD-01F classification , in accordance with the temperature to points, can also be classified according to the material , you can also follow the installation way points.
According to the nature of the action : the action can be divided into normally open(H Type) and normally closed(D type).
