Thermal Switch Manufacturing

Thermal Switch Supply<br />KSD301 series of products is the most widely used thermal switch. In Ya Xun, we provide high-precision dish-type bimetallic stamping, temperature classification, assembly, product testing one-stop service. Our product development for the needs of the market, there are a variety of different product size, different temperature control methods. If you are developing a new product, you need to know the product thermal protector, please contact our professional team, you can get a satisfactory offer and sample.<br /><br />What Is Thermal SwitchWhat Is Thermal Switch<br />KSD301 series temperature sensing element is a bimetal, is the most commonly used electrical overheating protection. When the electrical work, the bimetal is in a free state, the contacts are in the closed / disconnected state, when the temperature of the electrical appliance does not rise normally, when the protection action temperature of the Thermal Switch is reached, subject to heat effects Bimetallic, produce internal stress and rapid action, open / close contact, off / turn-on circuit, which play a protective role in temperature. When the electrical cooling to the reset temperature, the contact automatically closed / open, turn on the power, to return to normal working condition. KSD301 series of products can generally be repeated tens of thousands of times.<br /><br />Thermal Switch CharacteristicThermal Switch Characteristic<br />Stable performance, high precision;<br />Small size, light weight;<br />Not pull the arc, the structure of precision;<br />Can be reused, long life;<br />Widely used, the installation of diversification;<br />High Power, can be applied to large current electrical appliances;<br />Radio dry worry small.<br /><br /><br />  Fixed form: 1 - fixed aluminum cover, 2 - active ring free fixed, 3 - no fixed<br />Terminal posture: 1 - level; 2. vertical; 3-bend 45 °; 4. horizontal / vertical; 5-level / bend 45 °; 6. vertical / curved foot 45 °; 7 - no pin; 8 - other angles<br />Terminal type: 1-250 series; 2-187 series; 3-non-standard terminal<br />Operating temperature range Nominal value: 3 digits + On-off mode + 1-bit range absolute value.<br /><br />Control MethodThermal Switch Control Method<br />KSD series of temperature control after years of technology development, in order to adapt to the product of a variety of temperature control methods, in the Ya Xun, to meet the requirements of different customers, the development of a variety of temperature control products:<br />1. Automatic reset: changes or decreases with temperature, the internal contact is automatically disconnected or automatically closed.<br />2. Manual reset (anti-dry type): Mainly used in water heaters, when the temperature rises, the contact will automatically disconnect; when the controller temperature cooling, you must manually press the button to reset the contact again closed power.<br />3. Normally closed(NC): Electrical appliances work properly, the contact is closed, the thermostat is in power state, when the temperature reaches the operating temperature, the bimetallic sheet heat generated internal stress, and rapid action, open the contacts, cut off / on circuit, which play a role in temperature control.<br />4. Normally open type(NO): Electrical work, the contact is in the open state, the thermostat is in power state. When the temperature reaches the operating temperature, the bimetallic sheet heat generated internal stress, and rapid action, closed contact, connected to the cooling power supply, reducing the temperature of the heat generating element, which play a protective role.<br />5. Conventional electrical parameter type: 1) AC250V 50 ~ 60Hz 5A / 10A / 15A (resistive load)<br />                                      2) UL AC125V 50Hz 15A (resistive load)<br />6. High power type (KSD302): AC250V or 400V; 50 / 60Hz<br />                                            1) 16A; 20A; 25A; 30A; 35A<br />                                            2) 50A; 55A; 60A;<br />
