行程开关,位置开关(又称限位开关)的一种,是一种常用的小电流主令电器。
利用生产机械运动部件的碰撞使其触头动作来实现接通或分断控制电路,达到一定的控制目的。
通常,这类开关被用来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。
行程开关按其结构可分为直动式、滚轮式、微动式和组合式
直动式行程开关组成
1:推杆 2&4:弹簧 3:动断触点 5:动合触点
滚轮式行程开关组成
1:滚轮 2:上转臂 3511:弹簧 4:套架
6:滑轮 7:压板 89:触点 10:横板
微动开关式行程开关
微动开关式行程开关的组成,以常用的有LXW-11系列产品为例
1:推杆 2:弹簧 3:动合触点 4:动断触点 5:压缩弹簧
以LX19和JLXK1系列限位开关的主要技术参数为例(见下表):
