互锁门开关：安全可靠，防止意外启动

互锁门开关是一种用来检测门是否关闭的装置，当门关闭时，它会触发电路，以便设备能够正常运行。当门打开时，它会断开电路，使设备停止运行。它通常是由一个或多个接近开关组成，当门关闭时，接近开关会被推动，触发电路。

An interlock door switch is a device used to detect whether a door is closed. When the door is closed, it triggers the circuit so that the equipment can run properly. When the door is opened, it disconnects the circuit, causing the equipment to stop running. It is usually composed of one or more proximity switches. When the door is closed, the proximity switch is pushed to trigger the circuit.
