Why can micro switches last so long?

The core reasons why micro switches can last for millions of cycles lie in three aspects: optimizing the durability of easily worn parts, reducing wear during operation, and enhancing precision manufacturing processes.

The two most vulnerable parts of a micro switch are the contacts and the reed. The contacts are the part where current flows and are highly susceptible to arc erosion. The reed is the elastic part that controls the opening and closing of the switch. These two components directly determine the lifespan of the micro switch. The contacts should be made of materials that can resist arc erosion and wear. RENEW's micro switches use silver and gold-plated silver contacts, ensuring good conductivity while also improving arc resistance and wear resistance. Even after millions of cycles, the surface of the contacts will not be severely eroded or worn, ensuring stable conduction. The reed should be made of elastic metals. Ordinary metals will break when repeatedly bent.

The structural design of micro switches is very suitable for high-frequency use. The travel (the distance pressed) of a micro switch is very short, significantly reducing wear. The sealed design of micro switches isolates oil, dust, and other impurities, ensuring stable operation. Precision manufacturing processes are also a major reason for their long lifespan. Using automated assembly for precise installation reduces errors.
