🔌 Discover the Power of ARTGEAR Contact Normally Magnetic Induction Review

These are normally closed reed switches (on/no magnetic field, off/magnetic field) that work well with small magnets. I have found that the magnet needs to be positioned about 1/2 inch below or above the reed switch to permanently activate the switch. They are solidly built and sensitive. Ideal.

The glass is very fragile. Bending the legs in any way without first supporting the base of the wire will break the glass 100% of the time. But especially when I plug 5W into the switch for a few minutes, the tabs get stuck and won't switch with a magnet anymore. I've tried this on both the NO side and the NC side. After applying 5 watts of power to the switch for a few minutes, the reeds will remain attached to the rod you operated. I even tested it with 3W. Still stuck after a few minutes…

Technically they work, but no, as others have said, the tolerance is terrible. If the electronics on the test bench are available, I can easily open the circuit with a magnet, but finding a place in the application to get a reliable open circuit is very difficult. Make these particular unusable. I'm not sure if this is due to the bias magnet being too strong or if the supplied magnet is made more magnetized by using other magnets to open the circuit. I believe that will happen later. Because…
