Different types of electronic component switches are suitable for different application scenarios and have their own unique characteristics and functions. The waterproof performance of the switch determines its safety and also directly affects the safety of household electricity use. People are more likely to get electric shocks and get into danger if they touch the switch directly with their hands after washing their hands.
