Review on Set Of 6 Magnetic Reed Switches - Ideal For Door And Window Security - Normally Open And Closed For Flexibility In Monitoring - NC NO Design For Maximum Effectiveness by Phil Kuebler
Assembled backwards
I'm using this product for hatch lights on my boat. The only problem so far is they're backwards. NC (normally closed) light is off when doors open. Should be the other way. NC light is on when doors open. Not a huge deal, you can wire them to NO (normally open) position and they work just fine (on when door is open) not bad they're just backwards.
- Worked perfectly! I would use this product again
- The switches are relatively small and easy to overlook, which could mean that intruders could bypass them without even realizing they're there
