Precautions for 1. micro spring contact fingers


1. Circuit matching: When using miniature spring contact fingers, you need to pay attention to selecting the appropriate circuit to match, so as to avoid the problem of contact wear or circuit burning due to excessive or mismatched load.


2. Ambient temperature: The miniature spring contact finger needs to work in a suitable ambient temperature range, too high or too low temperature will affect its performance and life. Especially in a high temperature environment, it is necessary to pay attention to the influence of temperature on the material to avoid excessive baking deformation or relaxation.


3. Ambient humidity: The humidity of the use environment of the miniature spring contact finger also needs to be controlled within an appropriate range to avoid the problem of contact oxidation corrosion and electrical performance degradation caused by humidity.


4. power supply voltage: the application of micro spring finger contact equipment in the access to the power supply, need to pay attention to whether the power supply voltage meets the requirements, so as to avoid too high or too low voltage damage to the contact.


5. Transportation and storage: When transporting and storing the miniature spring touch finger, you need to pay attention to measures such as shockproof, anti-collision, and dustproof to ensure that it is intact.


Benefits of 2. miniature spring touch fingers


1. Fast response: The miniature spring contact finger adopts spring structure design, which can quickly respond to circuit signals and realize fast switch control. It can be applied to some special occasions, such as controlling high-speed motion equipment.


2. Long life: Because the miniature spring contact finger is made of high-strength materials, it has good wear resistance and corrosion resistance, so it has a long life, up to millions or even tens of millions of times.


3. Low contact resistance: The miniature spring contact finger is made of high-quality metal material, which has good conductivity when in contact, and can ensure the stability and reliability of the circuit.


4. Small size: Miniature spring contact fingers are usually made by precision machining technology, which can achieve smaller size and weight to meet the needs of various compact space layouts.


5. High precision: Because the miniature spring finger is usually used in precision instruments and electrical equipment, its precision requirements are very high, and it can reach the sub-micron level.


6. Flexibility: The design of the miniature spring contact finger can be adjusted according to different needs to achieve different contact spacing and strength, and improve its applicability in different environments.


7. Safety: Miniature spring contact finger adopts mechanical switch design, which is safer and more reliable than switch design based on semiconductor components.


In summary, the miniature spring contact finger needs to pay attention to selecting the appropriate circuit to match, avoid using it in an environment of too high or too low temperature and humidity, and pay attention to the power supply voltage. At the same time, the miniature spring contact finger has the advantages of fast response, long life, low contact resistance, small size, high precision, flexibility and safety. With the continuous development of science and technology, micro spring contact fingers will play an important role in a wider range of fields.
