    Limit Switch

    Compact, designed for plug and play with Blackbox controller, Easy to mount in tight spots, Especially useful on Z axis which has the shortest travel

    Although it is not yet connected, I have no doubt that it will work. I had a bad nut, wrote an email and about 2 days later received a nut and it fit. Great customer service!

    Easy to find and order. Only complaint (minor) is it had to be assembled (2 screws & spacer). Came on time, well protected, and works great . Mahalo
