Waterproof switches are electrical components designed to operate in wet or humid environments without malfunctioning. They are commonly used in outdoor applications, such as marine equipment, garden lighting, and industrial machinery, where exposure to water is likely. These switches are sealed with special materials to prevent moisture from entering and causing short circuits. The construction of waterproof switches often includes rubber gaskets or silicone seals that protect the internal mechanisms. They are rated by the Ingress Protection (IP) code, which indicates their resistance to water and dust. A higher IP rating signifies better protection, making these switches reliable for various applications.
