Reviewed in the United States on March 26, 2024
First of all, these are standard type reed switches that are used in most wired security system system window sensors. There are 2 small metal blades that are normally barely separated from each other inside a sealed glass tube. When brought close to a magnet, the magnetic field causes the 2 contacts to become temporary opposite magnetic poles and they are attracted to each other and close the circuit. When you remove the external magnet, the contacts are no longer magnetized and spring apart, thus opening the circuit. Usually, this would be called a normally open switch (ie: open circuit when there is nothing activating it), but the alarm industry tends to call these normally closed (because they consider the "normal" state of a closed window to have a magnet nearby). Anyways, these are the type that you typically want for a standard alarm system. In addition to the sensors, you also get the associated magnets.
PROS:
They are compact and look nice. The 2 wire screws on top are visible but don't stick out and could even be hidden with some white paint or tape. The ends with the screw holes can easily be cut off with a scissors to make them even more compact. They come with foam adhesive attached (but not all that sticky - see below). Somewhat easy to insert wires and tighten screws (if using straight solid wire that is not too thick - see below).
CONS:
The adhesive pad seems sticky but 4/5 sensors I installed had come loose by the next day. Best to remove the tape and use a strip of 3M mounting tape. The holes to insert the wires are a bit small; I found pushing a paperclip into each hole first helped somewhat. Some of my sensor wires are larger gauge stranded and these are fairly difficult to insert. The holes are definitely too small to allow me to tin the wire ends. Lastly, 2 of the sensors were stuck in the closed position after I mounted them - this defeats the whole purpose if they don't set off the alarm when the window opens. They unstuck with a couple taps (and then I degaussed them) and they work now but I suspect they had become magnetized while packed tightly with the included magnets (good quality reed switches should have little or no magnetic retentivity). I will definitely recheck all of them in a week or so to make sure all is still OK.
Overall, a good concept at a good price but a few details could definitely be improved upon.
