With the increase of air pollution and allergens, air purifiers have become a powerful assistant in improving the quality of life in modern households. The start stop device, filter status detection, and adjustment function of the air purifier all require micro switches to cooperate and achieve. Dongnan Electronics has developed micro switches such as KW4A (S) and KW10, which can be applied to air purifiers. The products have characteristics such as small clearance, sensitive response, long life, and anti vibration. They are equipped with multiple levers and terminals to provide you with professional micro switch solutions.
