Very fragile but work great!
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!

Fried the switch but it was probably my fault
Switch quality:They served their purpose successfully. I fried a couple by supplying too much amperage but was able to arrange a couple in parallel and make it work.The magnet is very sensitive and maybe a little weak. I glued the magnet to a croc jibit for the project I was doing and it was almost too heavy to use the switch.

Very happy with quality and functionality.
Very good quality and the contact has exactly what I was looking for. Wanted a wide gap switch and with testing the distance the contact changes state when the magnet is with in 2 inches of the contact.

Constant false alarms.
Poor switch quality. Poor value for money. Constant false alarms. Old Ademco contacts never false alarmed, this one I get lots of them even though the magnet never moves and is 1/8th inch from the reed switch.I should have known better really. I figure they were just all the same, guess not, lol… Cheap etc… Ordered Seco-larm, wish me luck, lol

Good quality
Good quality, easy to install. I used these to replace 2, 25 year old contacts that started to fail. Seems to have fixed the problem.

Break very easily
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.

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.
