Exactly as described, great quality. Will order more as demands sees fit. Thanks for the rapid shipping, and great price on your product (Door Contact Switches).

The quality is really nice, not that cheap feeling to it. The packaging was also good as well. Many diversified uses for this: gates, doors, windows, etc. Normally opened and normally closed. Most units on the market are just for one or the other.

I needed this to replace the sensor portion of an open-garage-door indicator light which I had purchased from Sears maybe 25 years ago. The other sensor had been smashed when the door tracks were replaced by a technician not familiar with my improvements.

It took me three mail order attempts to get the proper switch due to my misunderstanding of what "normally open" and "normally closed" means for a magnetic switch of this type. [It turns out that, even though the door is almost always closed and thus the switch is almost always in the field of the magnet, the descriptive literature thinks of the "normal" state as being when the magnet is removed, i.e., the door is open.] I finally came across this switch that has both NO and NC states, so that it can be made to work no matter what is the NO and NC convention.

It installed easily and works fine.

I was disappointed at this purchase. Regardless of what the manufacturer claims, this magnetic switch is more for a hobbyist than in a commercial application. I purchased it to add an additional sensor to the side door on my motor home, so the intrusion alarm would work on the side door in addition to the main front doors. The alarm system works through the dome light circuit. I ended up getting a magnetic switch from a friend of mine who does home and commercial alarm installations. Now is works like it's supposed to do. I would not purchase this product again for an identical installation.
