 当运动机械的挡铁(撞块)压到行程开关的滚轮上时,传动杠连同转轴一同转动,使凸轮推动撞块,当撞块碰压到一定位置时,推动微动开关快速动作。当滚轮上的挡铁移开后,复位弹簧就使行程开关复位。这种是单轮自动恢复式行程开关。而双轮旋转式行程开关不能自动复原,它是依靠运动机械反向移动时,挡铁碰撞另一滚轮将其复原。

其结构原理如图F2所示,当被控机械上的撞块撞击带有滚轮的撞杆时,撞杆转向右边,带动凸轮转动,顶下推杆,使微动开关中的触点迅速动作。当运动机械返回时,在复位弹簧的作用下,各部分动作部件复位。

滚轮式行程开关组成

1:滚轮 2:上转臂 3&5&11:弹簧 4:套架

6:滑轮 7:压板 8&9:触点 10:横板

滚轮式行程开关又分为单滚轮自动复位和双滚轮(羊角式)非自动复位式,双滚轮行移开关具有两个稳态位置,有“记忆”作用,在某些情况下可以简化线路。
