QitinDasen 20Pcs Premium GPS-14A Plastic Reed Switch, 2.5X14mm Contact Magnetic Reed Switch, Magnetic Induction Switch, Reed Contact Normally Open (N/O) Magnetic Control Switch

⚡ The wires are a bit short for my purposes, but they should suit most projects. I found that I could bend the wires without impacting the reed inside, which is positive; these potted reeds are a lot better than the bare versions, as they are far more robust, and having just broken another bare glass version, I am sticking to the potted variety in the future. I am using them to make door contact sensors for home automation, and they work very well. They are very similar to those in my existing Zigbee door contact sensors.⚡ I have used them equally for side-on triggering, and the reeds trigger well. With strong magnets, they seem to trigger equally well end-on. I have made discrete door sensors that are drilled into the door frame using a 9-mm hole, and I encapsulated the reed in shrink tubing. My application is for home automation multi sensor boxes using an ESP8266, and I could get away without a pull-up resistor as the board has it built-in. In summary, these worked perfectly for my application to make some really small sensors that were easy to install and also discrete. I needed to de-bounce the activation by 10 milliseconds on the ESP board, but that was the only slight complexity. They work very well, and I would have no hesitation about buying them again. ✔️

Bought to replace the flimsy glass reed contacts that came with a pre-made wiring loom for my organ pedalboard. I’m glad I made the upgrade. These are more sensitive and robust. Have used for a month with no failures.

Great items not easy to break unlike the uncovered glass type.The range is similar to the uncovered type.

A lot stronger than the glass ones much better

Looked ok good price for the quantity, but no magnets so couldn’t test or use them, information should state more clearly that magnets are not included
