The use of 1. miniature spring contact fingers


1. Automatic control system: Miniature spring contact fingers are widely used in automatic control systems, such as automatic doors, vending machines, automatic toilets and other occasions. These devices require fast response to circuit signals, fast switching control, and because of the small space constraints, small-sized miniature spring contact fingers are required.


2. Precision instruments: In precision instruments, it is necessary to use high-precision miniature spring fingers to ensure the accuracy of test data. For example, in scientific experiments, when certain substances need to be measured and analyzed, miniature spring fingers can be used for contact and control.


3. Electrical equipment: Because the miniature spring contact finger has the advantages of fast response, long life, low contact resistance, etc., it is widely used in various electrical equipment, such as switches, sockets, etc.


4. Communication equipment: In communication equipment, miniature spring contact fingers are applied to the on-off control and signal transmission of circuits, such as mobile phone buttons, digital camera shutter buttons, etc.


Maintenance method of 2. micro spring contact finger


1. Avoid humidity: Miniature spring contact fingers need to avoid contact with water or other liquids, because excessive wetting will cause contact oxidation and corrosion, which will affect electrical performance and service life. In daily use, the environment should be kept dry, while avoiding storage or operation in a humid environment.


2. Regular cleaning: In daily maintenance, the micro spring touch finger should be cleaned regularly to remove dust, dirt and other impurities on the surface. You can use a soft brush or cotton swab to clean, but should be careful not to use sharp objects into the contact inside, to avoid damage to the contact structure and cause damage.


3. Avoid overload: Miniature spring contact fingers need to be protected from overload damage. Appropriate circuits should be selected according to specifications when in use to avoid excessive load or too small, and to avoid contact burning due to excessive load.


4. Avoid high temperature: When using the micro spring contact finger, avoid the environment of too high temperature. Too high temperature will affect the hardness and elasticity of the material, resulting in deformation or relaxation. Before using for a long time, the temperature range of the contact finger should be checked first, and the working temperature should not exceed the specified range.


5. Avoid excessive vibration: Because the design of the miniature spring contact finger has an elastic structure, excessive vibration should be avoided during use to reduce damage to its mechanical structure. When transporting or moving miniature spring contact fingers, shockproof and dustproof measures should be taken to protect their mechanical structure and contacts.


To sum up, should avoid contact with water or other liquids, regular cleaning, protection from overload damage, avoid excessive temperature and excessive vibration, these are the maintenance methods of micro spring touch finger. Of course, the maintenance method also needs to be adjusted according to different types of miniature spring contact fingers. Through the correct maintenance method, the service life of the miniature spring contact finger can be extended, and its stable and reliable operation can be ensured.
