China Dust-Proof Switch   Manufacturers, Suppliers, Factory

From household appliances to industrial machines, micro switches are essential components in many devices. They mechanically switch the current on and off by means of a small lever or button that activates the contact mechanism.

In electrical equipment used in humid, water-rich and other special environments, the performance of Waterproof Button is directly related to the safe and stable operation of the equipment. Yueqing Tongda Wired Electric Factory, relying on its dedicated research and development as well as sophisticated manufacturing of this product, has set a solid industry benchmark in the field of waterproof switches.​

As the factory's flagship product, the Red Rocker Switch has been meticulously crafted from appearance to internal components. The red panel design is not only eye-catching, making it easy for operators to quickly identify and operate, but also stands out in dimly lit industrial environments, reducing the possibility of misoperation. Its internal quality is even more impressive. It uses a high-insulation shell material that can effectively resist daily bumps and wear. Even in dusty and humid environments, it can maintain stable operation.

In scenarios such as industrial equipment emergency stop, medical instrument safety circuits, and security system triggering, Push Button NC (Normally Closed Pushbutton Switch) serves as the "first line of safety defense". Its on-off reliability is directly related to equipment and personal safety. Yueqing Tongda Wired Electric Factory, which has been deeply engaged in the switch field for more than 30 years, has broken the pain points of traditional products such as "slow power-off response and weak environmental resistance" through specialized R&D on Push Button NC, providing stable and reliable safety control solutions for multiple industries.​

One possible reason for poor contact of the micro switch may be the adhesion of dust to the copper sheet or switch contacts. It is recommended to use sealed electric switches. Another reason is damage caused by harmful gases in the natural environment, which leads to the formation of insulating film layers on the surface of the joint.
