One, IP waterproof standard
The main evaluation standard for the waterproof performance of waterproof key switches is based on the ip waterproof rating standard. To see how the waterproof performance of the waterproof switch is, it mainly depends on the two digits XX at the back of IPXX. The first X is from 0 to 6, and the highest level is 6; the second X is from 0 to 8, and the highest level is 8; br /> The highest waterproof rating of the water push button switch is IP68.
Second, whether the certification is complete
The relevant regulations of ROHS, SGS certification; and have VDE/DEMKO/KEMA (now using EU ENEC), UL/CSA and other certifications. These are the certification requirements for high-quality waterproof key switches. If it is necessary to export overseas.
Three, other judgment criteria
The waterproof key switch has a reasonable design, long service life, high temperature resistance, high current shock resistance, and can meet the specific needs of your products, which should be considered.
The specific application of this waterproof key switch is restricted by many factors, such as: installation method and installation direction of the product, airflow, pressure difference acting on the product, strength of fluid rebound and working voltage; and so on. Even if the Arcolectric waterproof key switch with excellent sealing performance, its sealing technology has reached the leading level, it does not mean that the switch is completely sealed, and it is necessary to prevent the intrusion of corrosive gases or substances.
