　　基本定义：

　　行程开关，又称位置开关或限位开关，是一种常用的小电流主令电器。它利用生产机械运动部件的碰撞使其触头动作，从而实现接通或分断控制电路，达到一定的控制目的。

　　功能与应用：

　　CD4N-5D22行程开关主要用于限制机械运动的位置或行程，使运动机械按一定位置或行程自动停止、反向运动、变速运动或自动往返运动等。

　　在电气控制系统中，它起到实现顺序控制、定位控制和位置状态检测的作用。

　　广泛应用于各类机床、起重机械等设备中，以控制其行程及进行终端限位保护。

　　构造组成：

　　行程开关主要由操作头、触点系统和外壳组成。

　　在实际生产中，将行程开关安装在预先安排的位置，当装于生产机械运动部件上的模块撞击行程开关时，行程开关的触点动作，实现电路的切换。
