Very Small and Hidden Door Sensor
I was looking for a basic wired door sensor to install in my doors for Home Assistant and these were perfect, the sensor is so small it is hard to see it once installed, exactly the look I was going for.

Unreliable - DO NOT BUY!
These magnetic alarm sensor switches are low quality and totally unreliable. The switches (all 5 in a pack of 5) stick in the closed position once activated. Do not waste your time and money on these.

Had new windows out in and didn’t think to pull magnets so this worked well
Exactly what I wanted

These are NOT Normally Open switches. They are Normally Closed
Several other purchasers have noted this too. When you have these near its magnet partner, they close (there is no 'normally' in having the magnet nearby. When the magnet is away (which, in physics and real life) it is open. I knew these were mislabel, that is, I needed a normally closed switch, so I bought these as they did what I needed. I, and other purchasers, all wish these vendors, maybe outside the U.S., would spend a minute reading any number of sources available to get their naming right. Also, if I am wrong and I have been known to be in the past, someone please reply and let me know (and please reference your source). Thanks

Order extra
It's a good thing there were 5 units in the package and my immediate need was for two. I found that only two of the supplied switches actually worked. One was shorted closed and two others were stuck open no matter how strong the magnet was. If you purchase, test each unit before installing to avoid re-do's later.
