KJT heavy-duty limit switch is a mechanical control switch, which is used for conveyor belt deviation prevention, crane over-roll protection, and rope pull switch. Taking advantage of its high reliability, it is widely used in steel equipment, large conveying machinery, loading and unloading machinery and cement equipment. Resistant to harsh environments. The glass sealing joint is filled with inert gas
