Microswitch life is affected by a variety of factors, under normal circumstances can be used tens of thousands of times to hundreds of thousands of times, depending on the production quality, use of the environment and use of factors.
First, what is a micro switch?
Micro switch is a common mechanical switch, also known as "mouse switch", "micro keyboard switch", "touch switch", etc., mainly composed of contacts, springs, conductive plates, trigger rods and other parts. Its working principle is to make the contact switch on or off through mechanical force, and play the role of control circuit. Microswitches are widely used in electronic products, electrical appliances, instruments and other fields.
Two, microswitch life factors
The life of the microswitch refers to the number of times the switch can work normally, and this number is gradually reduced over time. The factors of microswitch life are more complex, mainly including the following aspects:
1. Material quality: the life of the microswitch has a great relationship with the material selected, and the hardness, wear resistance and corrosion resistance of the material will affect the life of the microswitch.
2. Mechanical structure: The mechanical structure of the micro-switch is another key to the life, whether the design of the mechanical structure is reasonable, whether the material of the spring, contact and other parts is appropriate will affect its service life.
3. Environmental factors: The use of the micro-switch environment also has a great impact, such as temperature, humidity, corrosive substances, etc., will have an adverse effect on the service life of the micro-switch.
4. Mode of use: When the microswitch is used normally, the life of the switch usually reaches hundreds of thousands of times. However, if it is used improperly, such as frequent bending, excessive loading, excessive vibration, etc., it will lead to shortened life.
Third, how to extend the life of the microswitch?
In order to extend the life of the microswitch, the following points need to be noted:
1. Choose good quality products: Choose a microswitch with reliable quality, which can ensure that the material and mechanical structure of the switch itself and the production process meet the standards and requirements.
2. Normal use: Use the micro switch correctly, do not overload, overload or rude use of the switch, to avoid frequent switching action.
3. Prevent environmental corrosion: Microswitches are usually not suitable for use in corrosive environments such as acid and alkali, and require some special treatment, or replace products with materials that meet the requirements.
4. Optimize the environment: The micro switch is used in a stable temperature and humidity environment to avoid moisture and heat or too cold environment.
5. Regular maintenance: For long-term use of micro-switches, regular cleaning and lubrication are required to maintain the surface quality and mechanical properties of the switch.
