The Guangdong Provincial Local Standards "Electric Kettle Temperature Sensitive Magnetic Switch", "Household and Similar Use Magnetic Temperature Control Switch" and "Household Appliances Bimetallic "Chip Waterproof Thermostat" was officially released recently and will be officially implemented on November 18, 2014. The issuance and implementation of these three local standards have improved the relevant technologies in the field of magnetoelectricity in my country.

"Electric Kettle Temperature Sensitive Magnetic Control Switch" and "Household and Similar Use Magnetic Sensitive Temperature Control Switch" two local standards stipulate that the control switch adopts thermal soft ferrite as the production material, which is different from the previous bimetallic temperature sensing material and traditional Compared with mechanical and electronic thermostats, their control accuracy is higher, performance is more stable, and life is longer.

The bimetallic waterproof temperature controller defined in the local standard of "Bimetallic Waterproof Thermostat for Household Appliances" has good waterproof characteristics, electrical performance and strong environmental adaptability, which overcomes the traditional bimetallic temperature controller. The shortcoming of poor reliability of the controller in the water.
