Configurable for normally open or closed. Quality. Great value. Eliminates guesswork. Perfect setup for me for low voltage closet lighting.
Worked fine, but the screws included are low quality and can strip easily if not careful. It needs a pilot hole to screw in.
I like that they came in a clear plastic box that made it easy to store unused ones. I used them to trigger LED cabinet lighting and they worked perfectly.
Having the ability to wire NO or NC is a great benefit that not all connectors like this offer. I will order these again for my next project.
I tried several different reed switches before I came to this one. I wanted to add LED lights to some closets and cupboards to make it easier to find things (and hopefully impress my wife).
The problem is that while online you will read that "Normally closed (N.C.)" means that the circuit is closed (electricity is flowing) when the magnet is NOT present, in fact every reed switch I bought was backwards.
Some did not work at all, but those that did took "normally closed" to mean that electricity flows when the magnet IS present. That is why I ultimately chose these reed switches; since they cover both operations, I figured they couldnt go wrong.
In fact, "normally closed" and "normally open" are still backwards on this reed switch, but I just connect to the "normally open" terminal and it works how I want.
When I open the door, electricity flows from the four AA batteries into the LED strip. I bought the battery pack and LED strip together, and simply cut a wire and inserted the reed switch into the circuit.
You can connect these reed switches either by adhesive strips or by screws. There isnt much difference either way. They are also durable and easy to use (with screw terminals).
They have arrows, too, whic...
