Very good quality limit switch.

I recently purchased and used this mechanical limit switch, and overall. I’m very satisfied with it. It feels solidly built and delivers stable performance. Not only can the lever be adjusted and rotated, but the head can also be rotated. This makes this model very flexible, and the toughness of its build makes it appropriate for heavy-duty use. If you’re looking for a reliable mechanical limit switch, I would recommend this one.
