How to avoid contact wear of Coaxial Switch
1. Control the use environment
Temperature and humidity: Maintain a suitable temperature and humidity environment. Too high temperature may cause the contact material to expand and deform, and accelerate oxidation; too high humidity may easily cause corrosion. Generally speaking, the ambient temperature should be controlled within the operating temperature range specified by the product, and the relative humidity should be maintained at 40% - 60%. The ambient temperature and humidity can be adjusted by installing air conditioners, dehumidifiers and other equipment.
Dust and anti-fouling: Dust and pollutants will form wear particles on the contact surface, aggravating contact wear. Install the coaxial switch in a closed cabinet or protective box to reduce the intrusion of dust and pollutants. Clean the use environment regularly to reduce the dust content in the environment.
2. Optimize electrical parameters
Control current and voltage: Avoid applying excessive current and voltage to the contacts. Excessive current will generate arcs and burn the contact surface; excessive voltage may cause breakdown discharge between contacts and damage the contacts. When designing the circuit, it is necessary to select the coaxial switch reasonably according to the rated current and voltage, and ensure that the electrical parameters during actual operation are within the rated range.
Reduce switching frequency: Frequent switching actions will cause the contacts to constantly contact and separate, increasing the chance of wear. In practical applications, try to reduce unnecessary switching operations and plan the frequency of switch use reasonably.
3. Choose appropriate materials and designs
Contact materials: Select contact materials with good wear resistance and high conductivity, such as silver alloys. Different contact materials have different wear resistance characteristics, and appropriate materials should be selected according to specific application scenarios and requirements.
Structural design: Optimize the structural design of the coaxial switch to ensure that the contacts are evenly stressed during contact and separation to reduce local wear. 4. Regular maintenance and inspection
Cleaning contacts: Clean the contacts regularly to remove the oxide layer and dirt on the surface. Special cleaning agents and tools can be used for cleaning, but be careful to avoid scratching the contact surface.
Check wear: Check the degree of wear of the contacts regularly. If severe wear is found, the contacts or the entire coaxial switch should be replaced in time to prevent performance degradation and failures caused by contact wear.
