Entering the industrial field, the importance of power switches becomes more prominent. On busy production lines, thousands of machinery and equipment require a stable and reliable power supply to drive. As the core component of power distribution and control, the performance of power switches directly affects production efficiency and safety. Once a malfunction occurs, it may cause the entire production line to come to a halt and even lead to safety accidents. Therefore, industrial grade power switches not only require high reliability and long lifespan, but also safety functions such as overload protection and short circuit protection to ensure the smooth progress of production activities.
