Allows you to have window part way open with an alarm.
Worried would not be able to leave window part way open with Ring alarm sensors. This definitely allows you to. Good magnets.

5.0 out of 5 stars Great replacement!
Reviewed in the United States on January 15, 2024
Our house came with a wired alarm system and I had one of these fail years ago. So of course I searched on Amazon and I found this 5 pack. It’s a simple magnet contact where one side is wired into the house wiring and the other side is a magnet. Had one of our originals fail last night. The hardest part was finding where I put the spares. 😃. Just completed the repair in five minutes. House alarm back to fully functional. Went ahead and ordered another five pack to keep them on hand.
