Temperature control switch is a temperature control switching element. According to the work environment (Heating objects) temperature changes, Temperature control switch within the physical deformation occurs, Resulting in some special effects. A series of automatic control elements for generating an ON or OFF operation (power source)Usually also called temperature control switch, Also known as temperature protection or temperature controller, Temperature switch, thermal protection, referred to as temperature controller. Through the temperature switch to send the temperature to the temperature controller, The temperature controller issues a switch command, Thereby controlling the operation or stopping of the electrical equipment, To achieve the desired temperature and energy saving effect.

Temperature control switch control mode classification:
Mechanical temperature control switch is divided into Vapor pressure type, liquid expansion type, gas adsorption type, metal sheet expansion type.
Wherein the vapor pressure type temperature control switch is divided into: Inflatable, liquid-gas mixed and liquid-filled type.
Household air conditioners, refrigerators, freezers are used in this type of thermostat.
Electronic temperature control switch is divided into: Resistive (thermistor) and thermocouple type.

Bimetal temperature control switch works:
KSD9700, KSD301 series is a bimetal as a temperature control components of the temperature controller. Electrical work properly, The bimetal is in a free state, The contacts are in the closed / open state. When the temperature reaches the operating temperature, Bimetal heat generated by internal stress and rapid action (Physical changes in the bimetals when heated), The contacts are automatically closed / opened. That is, cut off / connected to the circuit, which play a role in temperature control. When the appliance cools to the reset temperature, The contacts are automatically closed / opened(Bimetal cooling occurs when the physical changes (restitution)), Restore normal working condition.
Bimetallic sheet as a stable thermal protection material, Widely used in various electrical appliances. With stable performance, high precision, Small size, light weight, High reliability, long life, and other characteristics of the radio interference.
Bimetallic temperature control switch applications are as follows: Disinfection cupboards, electric water bottle, Coffee pot, electronic tile support, warm water bag, Drinking fountains, hair dryer, vacuum cleaners, electric heating stove, Microwave ovens, irons, dryers, Motor, electrical appliances Etc.
