10pcs Plastic Reed Switch Reed Contact Normally Closed Magnetic Induction Switch with 10pcs Small Multi-Use Round Magnets

Just Great Normally Closed Reed Switches LIKES: 1. EXCELLENT Product Function which is well described within the product description 2. Magnets INCLUDED which play a big roll with the reed switches operation 3. Solders Well DISLIKES: No dislikes currently

I bought these so that I had a weather proof way to power cycle a small IOT radio without having break open the case or add a physical switch. They do exactly what I need them to do and the included magnets were powerful enough to activate the switch through an ASA 3d printed case.

These are the worst product I ever spent my money on. I bought this for a project for a led light to turn on and off. You are better off using the normally open ones for better longevity without activating the magnetic function constantly. The distance that a magnetic needs to be near the sensor is so inconsistent. It cannot be touching it, sometimes it works in one direction and next time it works in another. When you decide it is working and mount it, it then refuses to shut off or activate. AFTER positioning this constantly the magnet just breaks the internal switch and it get stuck in one position. These are trash and purely cheap hobby toys. I gave up after trying two of them, ate the loss as I didn't want to return two bent switches of the batch and have them ship this garbage to another person. No way can these be reliable for permanent applications. Definitely should of listened to the bad reviews and saved my money.

The switched work very well on motorcycle trunk to light leds when opening lid. Placement of switch and magnets was a challenge but in the end works great.

I got inspired by magnetic switches after seeing how they work in escape rooms, and so wanted to buy some to try in small scaled projects. If you like to create puzzles that involve magnets to activate things, these would come very handy.

I prefer the glass bodied ones over the plastic ones. The magnets don't line up as they should and without being able to see the one in the body of the switch it takes * A LOT * of guesswork and trial an error to position it correctly.

The product works well. Had no defective ones. Fast shipping

This is a specialty item, they are very small and easy to epoxy to any surface..of course very little current but in today's digital world most things are low current.

Good

Die Schalter wurden pünktlich geliefert und funktionieren einwandfrei. Da das hier öfter Gegenstand von Diskussionen ist: es handelt sich wie beschrieben um NC-Schalter - d.h. ohne Anwesenheit eines externen Magnetfeldes ist der Stromkreis geschlossen. Ich habe den Schalter in der Klappe meiner Katzentür verbaut. Unterhalb der Klappe ist im Öffnungsmechanismus ein Magnet installiert der dafür sorgt, dass der Stromkreis bei geschlossener Klappe geöffnet bleibt. Bei Benutzung der Klappe wird der Schalter aus dem Magnetfeld bewegt, dadurch der Stromkreis wieder geschlossen und ein Wifi-Signal gesendet. Der Magnet muss dabei genau gegenüber dem Bias-Magneten (kleine Ausbuchtung) montiert werden. Also an der anderen Seite des Schalters. Das ist zwar in Anbetracht der Abmessungen der Bauteile etwas friemelig, aber zu machen. Ich benutze nicht die mitgelieferten Magneten. Die haben nach meiner Messung etwa 2000 µT (vergleichbar mit dem in der Katzentür verbauten) und sollten es in entsprechender Nähe auch tun. Klare Kaufempfehlung und der Preis ist dafür absolut OK!

Fast delivery

Ideal for my application, small enough to make installation very neat.

Lo he utilizado para encender y apagar unos leds al abrir una puerta y funciona perfectamente. Eso sí, los imanes que trae son un poco pequeños, por lo que estoy usando otros que yo tenía.
