desertcart.com: 2X Magnetic Reed Switch Normally Open Closed NC NO Door Alarm Window Security/Magnetic Door Switch/Magnetic Contact Switch/Reed Switch,DC 3V to 12v Lamp（White） : Industrial & Scientific

Review: So Far, So Good - The price is reasonable, it's easy to install, and versatile enough with systems that require either NO or NC. It's hard to say how long it will last since I just installed it a few days ago. This is a replacement for a similar item and manufacturer that lasted a whopping 28 days before failing. I'll give this one the benefit of the doubt for the time being and adjust the rating and review as necessary...
Review: So far, I like this product! - I use this switch with warning lights on my garage door. I install a 120v to 12v transformer in my garage next to my garage door opener. Then install two 12v lights in my room connected to my garage. When my garage door is open, the lights are on. When it is closed, they are off. I can always tell if I forget to close my garage door.

### ⭐⭐⭐⭐ It will not melt if you use it right.
*by K***Y on January 1, 2024*

I found this magnetic switch and it was more-or-less perfect for my application, but I couldn't help but notice all of the reviews of melted units. On further inspection you'll notice that many of these reviews detail misuse of the product by passing far too much current through it, for example to a lightbulb. This item uses a lightbulb as an example but explicitly says it should run to some sort of panel. This is a switch meant for powering a relay that can actually handle the current of your application. This is a switch for a signal, not for power. This will work great for something like an Arduino, but it will not for powering truck lights. Be warned that this is totally a Chinese wholesale product and you probably cannot pass through as much current as it says, but using it modestly will yield the intended result. Realistically you should not pass through 0.5A. You don't need much for a signal.
