Limit switches with a one-way lever plus roller actuator activate when an object depresses the top-mounted lever to activate a plunger. The lever angle is designed for one-way travel; the roller allows objects to pass easily. Available models include micro-sized and IEC-rated switches.
Limit switches with a one-way lever plus roller actuator are activated when an object forces a top-mounted lever to depress a metal plunger, activating a switch inside the unit. The roller, available in metal, plastic, or nylon, is used for contour following, allowing objects to pass easily, and has a lever angle designed for one-way travel. These limit switches are available in a variety of styles and sizes, ranging from economical micro switches to rugged, heavy-duty IEC switches.
