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 sealed contacts are filled with inert gas and are not affected by the environment. Resistant to vibration, impact, and wide range of applications.
