The life test standard of coaxial switch mainly involves the following aspects: Mechanical life test Test purpose: To evaluate the stability and durability of the mechanical structure of the coaxial switch under frequent operation. Test method: Usually, a special test equipment is used to repeatedly open and close the switch at a certain rate and stroke. For example, the switch is switched between the open and closed states at a certain frequency per minute. Judgment standard: When the switch has a mechanical failure, such as failure to open and close normally, contact damage, loose connection parts, etc., or its performance parameters exceed the specified range, the switch is considered to have reached the end of its mechanical life. It is generally required that the mechanical life of the coaxial switch should reach a certain number, such as 1000 times, 5000 times or even higher, and the specific value depends on different product designs and application scenarios. Electrical life test Test purpose: To test the ability of the coaxial switch to maintain good electrical performance during long-term use. Test method: Under specified electrical conditions, such as specific voltage, current, frequency, etc., the switch is repeatedly turned on and off. At the same time, during the test process, the electrical parameters of the switch, such as insertion loss, return loss, isolation, etc., are measured regularly. Judgment criteria: When the change of the electrical parameters of the switch exceeds the specified allowable range, the switch is judged to have reached the end of its electrical life. For example, the insertion loss increases by a certain number of decibels compared to the initial value, or the return loss deteriorates to below a certain value. Generally speaking, the number of electrical life tests also needs to meet certain requirements to ensure that the switch has sufficient reliability in actual use. Environmental adaptability life test Test purpose: To examine the life performance of the coaxial switch under different environmental conditions and evaluate its tolerance to environmental factors. Test method: Place the switch under different environmental conditions, such as high temperature, low temperature, humidity, salt spray, etc., and perform life tests according to a certain time period. For example, in a high temperature environment, keep the switch at a specified high temperature, perform a certain number of opening and closing operations, and then detect its performance changes. Judgment criteria: Determine the environmental adaptability life of the switch based on the performance changes of the switch under different environmental conditions. If the performance parameters of the switch exceed the allowable range within the specified number of tests under specific environmental conditions, it means that its life in this environment does not meet the requirements. Through the environmental adaptability life test, it can be ensured that the coaxial switch can work stably and reliably in various practical application environments.
