3 Sets NO/NC Black Magnetic Switch Wiring Recessed Door Sensor Hidden Window Contact Reed Switch for Access Control Replace Alarm System

Worked great to turn dome light on-off of my UTV when opening-closing of either door. I even have a spare. (I did use an interposing relay)

Perfect, I loved.

These little switches caused me so much headache, because they just quit working out of nowhere. The voltage and amperage were well within specs. I bought six because I needed four. I wired them in first by just twisting the wires. They worked. I then soldered and heat-shrunk the connections. They worked. I mounted them to the doors and cabinet, but one of them didn't work. I replaced it, and one of the others quit working after a day. I was convinced for a while that something was faulty with my wiring or mounting. Turns out these are junk.

Included directions would be nice….used for Ratgdo32 Blue (C) is essentially a ground wire. I used black (normally closed) as my wire for when it would trigger it to turn on when they are close when magnet is near the sensor. White (normally open) would conduct when seperated, turn off when together

Worked as expected. Was good to find out that the switch worked no matter what side the magnet was placed.

on these magnetic switches the blue wire is the common ground the black wire is for nothing working when magnet is touching! I used this to replace the switch in a safe for lighting! Other thing to know it was a 6 volt system , that used 4 aa batteries , that I replaced with a 5 volt 2 amp amazon cell phone charger seen in picture un shelf!

Only one of the 3 worked. I one needed 1, but i bought 3 to have spares, so the one worked great and I repaired my project.

Work perfectly. I used them in my under the stairs closet. I installed some LED light strings on the ceiling in the closet and installed this switch on the wall, wiring it through a MOSFET power relay. When you open the closet door the lights automatically turn on, and they turn off when you close the door. It seems like the lights are always on because as soon as you open the door its illuminated, but of course that's not the case. I didn't need 10 or 15, so this was the only listing I found that had only a couple for a good price. The magnetic sensors already being wired made installation a breeze.

Es un pequeño gran producto, ya que se pone la tecnología industrial al alcance de todo usuario.

Fais le job

En av magnetströmbrytarna fungerade inte!

Habe Türkontakte damit realisiert. Durch den NC und NO Anschluss lässt sich auch über längere Kabelstrecken eine zuverlässige Schaltung verwirklichen.

works as intended
