互锁门开关 - 电气安全保障，防止意外事故

互锁门开关主要用于门窗等设备的电气互锁，本产品主要由开关本体、接点和作动件组成，当门开启时，开关上的凸轮通过联动，将作动件旋转，接点闭合，形成电路。当门关闭时，凸轮返回原位，接点分离，断开电路。一般与接触器、继电器等电气元件配合使用，形成电气互锁系统，有效防止门窗开启导致的意外事故。

Interlock door switch is mainly used for electrical interlocking of doors, windows and other equipment. The product is mainly composed of switch body, contact point and actuator. When the door is opened, the cam on the switch rotates the actuator through the linkage, and the contact point is closed to form an electrical circuit. When the door is closed, the cam returns to its original position, the contact point is separated, and the circuit is cut off. Generally, it is used with contactors, relays and other electrical components to form an electrical interlocking system. It can effectively prevent accidents caused by door opening and closing.
