To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching!
Posts on switch are COM, NO, NC. Resistance measurement from COM to NO without magnet present is short. From COM to NC without magnet present is open. I believe the NO/NC markings are not standard usage. The switch works well. Its just confusing.
good replacement for ADT mag switches
The mag switches on my windows broke, so i installed these and they work perfectly. Thanks MPJA!
