    Xtension Limit Switches

    This is a fantastic product, I had made my own switches in the past, but always had the problem on the direction of the switch, the ability to reverse the switch before placing it is great. The built in filters also give a cleaner signal.

    Awesome upgrade!

    Posted by Andy on Jun 28th 2019

    I was using some old limit switched I had laying around on my CNC C-Beam machine, and these were an excellent upgrade when I moved to the BlackBox controller. I love the way the standoffs are setup and really dig the fact that both the top and bottom are labeled with pin identification.
