Recommendation: When selecting for industrial control scenarios involving membrane switches, the three core applications are automated production lines, industrial robots, and CNC machines. These require a waterproof rating of IP65 or IP67. Sample testing is a reliable method to verify the reliability of the product. It is essential to fully validate this in the IP65 or IP67 waterproof testing.
