6PCS Micro Limit Switches with 1M 3 Pin Cable for 3018-PROVer/3018-MX3/3018-PROVer Mach3

Fit my 3018 PROver perfectly. I only needed one piece and did not need the wire so I left we 5 switches and 6 wires. The quality of the part is very good and it works as it should. If another one breaks, at least I have extras.

Compact switches

I have a Genmitsu 3018 Pro, which is apparently different from the 3018 PROVer. My board has 2 pin inputs for the limit switches, and these are 3 pin. I was going to make a breakout board so the LEDs will function, but these are 12v and my machine is 24v, so I'd also have to make a voltage regulator or a secondary voltage input which is an awful lot of work for this machine, LOL.

I am creating a printer that is now obsolete, however, not the fault of these limit switches. Measurements are ture from the first to the last application. AND I didn't have to make wiring harnesses!

They worked fine. I actually sanded down the slightly raised PCB on the switch side and directly glued them to appropriate places on my CNC 1419. Only lost 1mm of travel for each axis. Easily undone, and required no fixtures or drilling. The supplied cables work if you have 6 limit inputs. If you have only 3, you can fashion the supplied cables into "Y" cables with mild soldering skills and some heat shrink tubing.

Great product. Great price.

Genmitsu 6PCS Micro Limit Switches with 1M 3 Pin Cable for 3018-PROVer, This is not compatible with the board sent with the Genmitsu 3018 PRO Ver, I'm not sure that it's compatible with any of them, the board sent with my Genmitsu 3018 PRO Ver only has 2prong input connectors. I even bought the other controller board "SainSmart Genmtisu GRBL Controller Board for CNC Router Machine 3018-PROVer/ 3018-PROVer Mach3/ 3018-MX3" this didn't even fix the issue, this control board couldn't even be recognized or connect with the software even though it's description clearly states that it will, if you go to their website it's actually the only control board that they offer.

The mounting holes on my new 2018 Plus match these parts, however the bottom of the part (conveniently not shown in the several pictures) have several protruding uneven uninsulated electrical connections. I cannon install these on my metal frame without creating a short, and they do not lay flat. One YouTube reviewer shows mounting using thick double sided tape which seems like it might work. Note there are no mounting screws included creating the need to make a trip to local hardware store, and also guessing the right length and diameter of screw.
