10pcs Plastic Reed Switch Reed Contact Normally Open (N/O) Magnetic Induction Switch (3mm×14mm)

I bought a pack of these a few years back and they were 100% reliable. Then I bought some different ones that looked the same but they were flaky so when I needed some more I went back to these. So far so good.

They do exactly what they're supposed to do! Just make sure to not try to run more than the rated 0.5A through them, or the contacts will fuse.

Works like it should. No issues.

This worked great to replace my old broken magnet switch on my college project. We made this in mechatronics class to help understand electric motors. My son smashed the old one. The switch needs some time to break in the new one was stiff of course.

They seem to work fairly well, only occasionally getting stuck closed. Be careful to handle gently or the glass can break. Next time I'll try plastic housing versions.

Switches arrived quickly, tested snd installed into project, the switches worked better than I expected. Very sensitive and work every time. Great well built product.

The glass ones were unusable. These immediately worked for my application. I didn't have to replace the magnet in the submersible device.

Wish I read the critical reviews before buying. Given so many positives I thought for this price why not? I did some preliminary testing and though they were a bit finicky but seemed usable. When I soldered them to some lead wires I soon realized that after use they would stay closed and did not release. I spent hours 3d printing components to use this for a project that required a certain order of positioning based on the magnets and reed switches have to scrap the idea because I went with these cheap switches.
