good item, does detect at 15mm, as described
Good item, works fine, I was a bit worried about the distance for detection, but when I tested these it was almost exactly 15mm distance for detection, which was plenty for me.

Great double pack!
This double pack of magnetic contact reed switches is a great buy for DIY home projects, with fixings included for installation. The quality is what you pay for. While the quality seems good, it feels basic and I worry how it may hold up over time. However so far, they are working brilliantly.

Works as expected
Connected these to an ESP32 and then stuck to my door. ESP32 is running ESPHOME which is then connected to Home Assistant. I get instant notifications when the door is open. These reed switches aren't overly sensitive so they do have to be quite close together to actually get the 'closed' signal. They were extremely easy to setup and good value for money.

They work, no issues. Fast delivery.
Simple, quick, no problems, I would have preferred a PVC-PVC coated two core cable rather then two separate PVC core cables as it looks tidier but they did the job fine, I have them installed and they work. No issue.

NO switch not NC
It's a normally open switch. NO. Not as the ad describes NC. Duh!

Pretty good and reasonably sensitive
These are pretty good. Quite sensitive and the reed switch closes when the magnet is about 1cm away. Comes with screw holes in the reed switch and magnet, screws and sticky pads to secure them. Probably about 1ft of wire from the reed switch which does go into breadboard.

Good what it does, but size is small

Je cherchais des capteurs de position/fin de course plus fiables dans le temps que les micro interrupteurs. Je suis ravi, ils fonctionnent parfaitement pour une détection sans contact. Ils sont entièrement noyés dans de la résine, donc normalement insensibles à l'humidité et au gel. Reste a voir dans le temps...

Ich habe diese Kontakte in Kombination mit einem Shelly Plus 1 und dem Add-On-Modul installiert, um die Garagentor-Position zuverlässig zu überwachen. Die Sensoren sind simpel aufgebaut, funktionieren aber absolut zuverlässig – genau das, was man braucht. ⸻ ✅ Vorteile im Alltag: • Magnetkontakt reagiert präzise – bei wenigen Millimetern Abstand sauberer Wechsel von geschlossen/offen • Anschlusskabel ausreichend lang, lässt sich leicht kürzen oder verlängern • Gehäuse schlicht, weiß, unauffällig, ideal für Fenster, Türen oder Tore • Funktioniert mit Shelly, ESP32, Arduino oder Alarmanlagen ohne Probleme • Montage mit Schrauben oder Klebestreifen möglich – je nach Untergrund ⸻ 🧠 Praxiseinsatz (mein Szenario): • Sensor am Torrahmen, Magnet am beweglichen Teil • Angeschlossen an Shelly Add-On → App zeigt sofort Status (offen/geschlossen) • Seit 2 Wochen ohne Aussetzer oder Fehlfunktion – auch bei Temperaturschwankungen in der Garage ⸻ 📌 Fazit: Günstig, einfach und effizient. Wer smarte Zustandsabfragen in Home Assistant, Alexa-Routinen oder einfachem Alarmaufbau integrieren will, ist mit diesen Kontakten sehr gut beraten. 5 von 5 Sternen – tut genau das, was es soll, zuverlässig und ohne Schnickschnack.

Die Leitungsenden waren etwa 3 mm abisoliert, hatten aber in den Klemmen keinen richtigen Kontakt. Nach anderweitiger Fehlersuche ohne Erfolg und Trennung der Leitungen, weiterer Abisolierung funktionierte es auf Anhieb. Alles bestens.
