Cylewet10Pcs Reed Switch Normally Open (N/O) Magnetic Induction Switch Electromagnetic for Arduino (Pack of 10) CYT1004

Bon produit à bon prix!

Awesome little switches. I purchased these for a little 3d printed 22re engine. The switches work great near a magnetic field, but be sure to verify they do work. Please be careful, the glass body looks good but break very easily. I broke several while trying to get them into my 3d print and at one point I had a piece of glass go into my eye. This was my fault and not the products, just be careful if you are near sighted like me.

These work exactly as expected. I'm using one to sense a magnet spinning inside a brass tube with the reed switch mounted outside the tube wall. Being of glass, the reed envelope is fragile, while the iron leads are quite stiff. One must take care to not expose the glass envelope to bending forces while forming the leads.

Like others, found that you need to be very careful while using these, due to being fragile.So far, I have found 3 out of 5 that are not working properly.From what I can tell, the sensitivity seems to be lowest right in the middle of the device.I should have read the comments first, and bought something more robust and reliable!

I'm using them for a 5 volt, 4 mili-amp application. As of this review, it's about 20,000 cycles in with no issues. I'm trying the first one without a capacitor, and it seems to be doing fine. I'm sure it will eventually degrade, and the next one will have a cap. My application is using a stack of neo-mags. The switches are quite sensitive and require some distance. They arrived well packaged, and in good shape.
