FAQ

The ME-8108 is rated for 5A at 250V AC or 0.4A at 115V DC. It features a double-circuit limit switch mechanism with a 1NO (Normally Open) and 1NC (Normally Closed) contact configuration.
This switch is commonly used in CNC mills, laser cutters, plasma tables, and various industrial automation applications. It is designed for use in any machinery requiring precise position detection or end-of-travel limits.
The roller lever arm can be rotated 360 degrees around the axis of the switch head. You can loosen the screw on the lever arm to adjust the angle to your specific mounting requirements, then tighten it securely to lock it in place.
You should consider replacing the switch if you experience intermittent signal loss, the machine fails to stop at the designated end-of-travel, or if the mechanical lever arm becomes loose, stuck, or fails to 'click' when depressed.
Installation typically requires a small Phillips or flat-head screwdriver for the terminal screws, a set of mounting bolts (usually M5) to secure the switch body to your frame, and a multimeter to verify continuity across the NC/NO contacts before finalizing your wiring.
The ME-8108 features a sealed design that provides protection against dust and light moisture. However, for heavy-duty outdoor use or environments with direct coolant spray, we recommend adding an additional protective enclosure or shroud to extend the life of the internal contacts.
