Work perfectly for a low power LED light string to automatically turn on/off via proximity on door.
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.

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.

Good Product
If these would ship with a simple set of instructions that give wire colors relating to switch functions, it would save the installer some time and frustration. Also, it’s nice that they supply attachment screws, it would have been even nicer if they were the correct type of screw. The encapsulated reed switches and magnets appear to be well made and they function great.

Works perfectly and attached to my existing alarm without issue.
Worked perfectly! I have a security system with door/window open alarms. One of the sensors got damaged and these spliced right onto the alarm unit meaning I don’t have to replace the entire alarm. I only needed to replace the damaged sensor end. Saved me a bundle.

Failed
Failed after 1 week. I am. Installed on liftgate of truck, tested and 1 failed before it was fully installed. 2nd attempt installed tested lasted a week. Problem the sensor becomes very sporadic and sensitive and weak. The magnetic that comes with it can no longer trigger it. Put small tiny earth magnetic to see if that made a difference. It is only triggering sometimes. Disappointed in such a simple product.

One was broken and another one had a huge sensing delay…Although there was a problem the item could be returned without any issues even with a peace of wire stripped off to test them…Product was below average for my use case, but the way it was handled afterwards was easy and costumer friendly!5 stars for service, Making an average of 4 stars in total!

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