10pcs 4W 3 Pin Reed Switch Reed Contact Normally Open N/O N/C SPDT, Glass Reed Relay Magnetic Induction Switch (2.5mm x 14mm)

I gave my wife one of those book nook craft kits for Christmas. When she finished assembling it I wired it up. The capacitive touch switch for the tiny LEDs was very poor quality. Occasionally it would turn on, confirming I had wired it correctly, but it wasn't remotely reliable. The theme of the set was magic house (a Harry Potter / Hogwarts knockoff), so I told her I would fix it with magic. I ordered these. I broke the first two as I tried to get it into position, but the third one worked great. I buried a tiny neodymium magnet inside the bristles of a TINY broom and now when she moves it to a particular corner of the room the lights turn on. The reed in these switches have to be sensitive enough to move from the field from the little ~1/8" magnet through 1/8" of plywood and a little additional gap from the placement inside the broom. Very impressive!

Used this set to repair my Gazelle exercise machines fitness computer. Switches work better than the original, and although the magnets are a lot smaller than i expected, they are super strong. Check your measurements! Great set for repairing this type of circuit.

I am very happy with these switches They work great and operate in either normally open or normally closed modes. There is a great short video of these operations on circuitapps YouTube channel, if you want to get a better understanding of these modes.

i got the metal version for a diy alarm system. tested it with my arduino and it works great! the option for nc and no is a great touch to the overall build.aproved

There’s this interpretation that if you know what you’re doing, you will draw it out first. And usually the rule of thumb goes to sign your name to your work. Now, mechanics are very busy and the math only proves that if warranties are associated with financing, then real estate is only a cup of tea. – That leaves picnic tables outside of bins & boxes with a set of stairs waiting to open warehouse docking doors.The fleet never travels farther than the farm.

Value for the money - 0/10.Quality - 0/10Waste of money its garbage! 30% stuck open! The rest work 2/3 time and stuck also. It’s absolutely scam.

I guess this is to be expected, since they're glass. But they break so easily that I shattered two of them just bending the leads down to plug them into a breadboard. If you don't necessarily need them to be glass then I suggest you go with the plastic case.That said, they work perfectly, as long as you don't break them. And in fact, they actually still work when the glass case is shattered. But if you both break the glass and pull the leads apart, which is very easy to accidentally do with these, then it won't work.Also the magnets are absolute garbage, they're weaker than my fridge magnets and have to be just about touching the reed switch before it will flip. The reed switches work great if you use a different magnet.As long as you actually need the glass ones, these are as good as any.

Nifty little devices, but you must take extreme care when bending or cutting the wires. The side that reacts the best to magnetism seems to be the side with the two faint black circles. I used them in some proximity keys for a car, and these keys did not have an "off" feature (kinda silly). The key is normally off now, unless my magnetic ring is nearby.Highly recommend doubling / tripling these things up for redundancy and using stronger magnets with them.

Solid aluminium body, with resin encased reed switch & magnet. Switch activated max 20mm away, providing a reliable signal.SS screws provided, but of relatively soft metal, so only OK into softwood.
