The service life of auxiliary switches is affected by a variety of factors, such as the use of the environment, electrical properties, mechanical properties, corrosion resistance and maintenance. The specific analysis is as follows:

1. Use environment:
    Auxiliary switches need to work in a specific temperature range, the general operating temperature range of 40 ° C to +80 ° C, if the ambient temperature beyond this range, may affect its performance and life.
    The level of protection is also an important consideration. Indoor environments may only require an IP20 rating, while outdoor or harsh industrial environments may require a higher IP65 rating.
    Vibration and shock are common problems in industrial environments. Auxiliary switches should have a certain level of vibration and shock resistance.

2. electrical performance:
    The rated current, voltage and switching capacity of the auxiliary switch must be selected according to the application requirements to ensure long-term stable operation.
    Electrical faults, such as overload or short circuit, will seriously affect the life of the auxiliary switch, so the electrical circuit should be inspected regularly to eliminate hidden problems.

3. Mechanical performance:
    Poor contact points may cause the switch not to close properly or the contact resistance to increase, affecting the service life. Regular cleaning of the contacts or replacement of the contacts will help maintain their performance.

4. Corrosion resistance:
    When working in a chemically corrosive environment, materials with high corrosion resistance should be selected or specially treated to ensure long-term stable operation.

5. Maintenance:
    Regularly check the status of the auxiliary switch, including contact wear, loose cable connection, etc., and repair and replace it in time.

6. Product quality:
    Different auxiliary switch products differ in design, material and process, and the quality directly affects the service life. For example, ZKF series vacuum auxiliary switch adopts vacuum reed switch technology, which has 100,000 times contact life and maintenance-free performance.

7. Mounting method:
    Correct mounting can reduce damage to the auxiliary switch from external forces and prevent additional wear caused by improper installation.

Overall, when selecting an auxiliary switch, its operating environment, electrical parameters, mechanical properties and corrosion resistance should be taken into account, and attention should be paid to the maintenance and care of the product in order to extend its service life. For specific applications, such as those that require stable operation for long periods of time and inconvenient maintenance, it is recommended to choose products with reliable quality and long service life, such as vacuum auxiliary switches. Regular inspection and maintenance is the key to ensure the long-term stable operation of auxiliary switches.
