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.

These switches are tiny. They are made out of plastic instead of glass. My wife stepped on them and they were just fine. They are thin and can be used in very small spaces and very discretely. The are build tough and will handle a lot of abuse. Good way to mount them would be to glue them in place. I made a little grove and used tape to keep them in place. Since you get 10 switches, the value is a good value. Opposite from the switch I placed a magnet to activate the switch. They work well

Be sure to check for operation. One of the 10 was bad. Not worth returning the whole order to correct. There should be an easier way. Otherwise should work nicely for any applicable use.

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.

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

Very happy with these reed switches. The switches were as described. Used one to repair a sensor whose reed switch had failed.

Used these in an HO coach car to turn the lights on and off with a magnet and some circuitry. I like the plastic case as well, because it is harder to break than the glass ones.
