3D Printer Part Limit Switch with Separate Package CNC for RAMPS 1.4 RepRap 3D Printer CR-10, Ender 3/3 Pro/3 V2/5 (Pack of 3)

These limit switches were perfect plug and play for my Ender 3V2 printer. Installed and away we went. Good quality.

My X axis limit switch got smashed in (somehow) and needed a new replacement for it. Came with a few so I have some backups.

My cat stepped on my end stop switch and broke it. So i ordered this and got a couple extra for the next time my cat brakes it. Its a direct replacement from the stock part, and it was easy to replace. Unplug and unscrew the old one. Screw in and plug in the new one. Simple as that.

Turns out I had a defective Z limit switch on my Ender 3v2, so when auto homing, the nozzle would lower but the limit switch wouldn't engage at the same spot/pressure every time. So much so that sometimes i'd hear the switch *click* and sometimes it wouldn't even get that far before cutting out. This means I'd level the bed to one height, and then when I'd start a print and it'd auto home before beginning extrusion, the nozzle would be higher or lower than I just leveled it to. I got these little switches and swapped it out in less than 5 minutes and it's been printing like a dream ever since! Highly recommended if you're having issues.

Works great, just what I needed. When I first put together my ender 3, the metal "clip" for one of my axis fell off so I was getting issues with the head just grinding into the side of the printer until the button for the stopper got activated. I bought these, unscrewed/unplugged the broken stop, and put this one in. Worked perfectly, and now I have 2 extra if I ever need them!

It was nearly a drop-in replacement, but I had to drill the mounting holes out to get it to fit the plastic mounting block on my Ender 3 Pro. Just had to go 0.8mm larger on the holes (1/32 inch). Before I did that, I couldn't get the stock printer screws or socket cap screws to fit past the electrical connector.Still, I would buy these again.

this fixed the problem of my Z axis switch not double clicking when starting a print.. causing the first layer to not be at the correct level.. a quick swap and now it starts the first level at the proper height.

Z leveling was always flaky on my ender. Could home it a few times, and it would find its place, but this got tiresome. Tried swapping with the Y switch, but it was worse. Was leery about buying them from the same company, but these seem to have fixed it for now. There might be a good market for higher-quality aftermarket replacements. Someone please get on that!

As advertised giid price worked.
