WL series limit switches Features:Double-circuit type of limit switch, is widely usedWith strong aluminum cast outer shellHigh mechanical strengthWater-proof, oil-proof constructionStructure preventing oil, water and pressureIndicating plate with setting position is installed in it, so it is easy to maintainVarious of actuators is taken convenience for using
Built-in contact stand has double-spring, so it has long mechanical life
