Name and Classification of Temperature Protectors
Temperature control switch is divided into mechanical and electronic. Electronic temperature control switch generally uses thermistor (NTC) as the temperature sensing head, the resistance value of thermistor changes with the temperature, the thermal signal into electrical signal. This change pass...Read more -

The Construction and Performance of NTC Thermistor
The materials commonly involved in the manufacture of NTC resistors are oxides of platinum, nickel, cobalt, iron and silicon, which can be used as pure elements or as ceramics and polymers. NTC thermistors can be divided into three classes according to the production process used. Magnetic Bead T...Read more -
NTC Thermistor Temperature Sensor Technical Terms
Zero Power Resistance Value RT (Ω) RT refers to the resistance value measured at a specified temperature T using a measured power that causes a negligible change in the resistance value relative to the total measurement error. The relation between resistance value and temperature change of elec...Read more -
The Structure, Principle and Selection of Fuse
Fuse, commonly known as insurance, is one of the most simple protective electrical appliances. When the electrical equipment in the power grid or circuit overload or short circuit occurs, it can melt and break the circuit itself, avoid the power grid and electrical equipment damage due to the the...Read more -
The Application of Bimetal Thermostat in Small Household Appliances – Electric Oven
Since the oven tends to generate a huge amount of heat, it requires maintaining an appropriate level of temperature so as to prevent overheating. Thereby, there is always a thermostat in this electric device that serves this purpose or prevents overheating. As an overheating safety protection co...Read more -
The Application of Bimetal Thermostat in Small Household Appliances – Coffee Machine
Testing your coffee maker to see if the high limit has been reached could not be easier. All you need to do is unplug the unit from the incoming power, remove the wires from the thermostat and then run a continuity test across the terminals on the high limit. If you notice that you do not get a...Read more -
How to Install a Refrigerator Defrost Heater
A frost-free refrigerator utilizes a heater to melt the frost that can accumulate on the coils inside the freezer walls during the cooling cycle. A preset timer typically turns on the heater after six to 12 hours regardless if frost has accumulated. When ice begins to form on your freezer walls, ...Read more -
Refrigerator Defrosting System Operation
Purpose of Defrost System The refrigerator and freezer doors will be opened and closed numerous times as family members store and retrieve food and drink. Every opening and closing of the doors allows air from the room to enter. Cold surfaces inside the freezer will cause moisture in the air to ...Read more -
The Application of Bimetal Thermostat in Small Household Appliances – Rice Cooker
The bimetal thermostat switch of the rice cooker is fixed in the central position of the heating chassis. By detecting the temperature of the rice cooker, it can control the on-off of the heating chassis, so as to keep the temperature of the inner tank constant in a certain range. Principle of ...Read more -
The Application of Bimetal Thermostat in Small Household Appliances– Electric Iron
The main component of the electric iron temperature control circuit is a bimetal thermostat. When the electric iron works, the dynamic and static contacts contact and the electric heating component is energized and heated. When the temperature reaches the selected temperature, the bimetal therm...Read more -
The Application of Bimetal Thermostat in Small Household Appliances — Dishwasher
The dishwasher circuit is equipped with a bimetal thermostat temperature controller. If the working temperature exceeds the rated temperature, the contact of the thermostat will be disconnected to cut off the power supply, so as to ensure the safety and reliability of the dishwasher. In order t...Read more
