Indeed, the lifespan of key switches is an important consideration, especially in applications that require long-term stable operation. Conducting experimental verification can help evaluate the reliability and durability of key switches.

Here are some possible experimental validation methods:

1、Button lifespan test: By setting up an automatic button pressing device, simulate the usage of the button, record the number of times the button is pressed and the state after each press. A criterion can be set in the experiment for a button to be considered invalid, such as a button failure or a button resistance value exceeding a certain range.

2、Environmental testing: Place the button switch under different environmental conditions, such as high temperature, low temperature, high humidity, low humidity, etc., to observe whether the performance of the button is affected and whether its lifespan is shortened.

3、Vibration test: Simulate the vibration of the equipment during transportation or use, observe whether the buttons will malfunction or have a shortened lifespan due to vibration.

4、Electrical parameter testing: Monitor the electrical parameters of key switches, such as contact resistance, insulation resistance, conduction time, etc., and change them with increasing usage to evaluate the performance changes of the keys.

5、Reliability testing: Within the design lifespan of the button switch, continuously use the button and regularly test its performance to evaluate its reliability and stability.

Through these experimental verifications, the service life and reliability of key switches can be comprehensively evaluated, providing strong reference for product design and ensuring that the product can work stably and reliably within the expected service life range.
