Technical Specifications Product Name : Magnetic DoorContactReed Switch Material: Anti-fire ABS shield,Color: Black Connecting mode: N.C./N.O conbined Rated current: 500(mA);Rated voltage: (VDC)100;Rated power: 10W Operating distance: more than 15mm, less than 25mm Dimension:55*12.5*11.5mm; Mounting Hole Size : 7 x 2.5mm/ 0.28" x 0.1"(L*W) Application Recommendations in application: wooden door, window, metal doors, gates and any other compatible application. Installation Instructions The door and window magnet should be installed at the closed position of the door/window. The magnet part is installed on the movable door and window. The switch part is installed on the fixed door and window frame. The switch part and the magnet part should be aligned as much as possible. NOTE The Magnetic Door Switch must be installed according to the sensing distance; It can only provide a switch signal to the device, which cannot directly load the power, nor directly connect the lamp! The door magnet should be away from the strong magnetic field interference source such as a transformer. Otherwise, the working characteristics of the door magnet will be changed and possible wrong actions. About Normally Closed and Normally Open N.C. / N.O. Definition N.C. means Normally Closed: When the magnet together, the circuit is conductive( light on ); When the magnet separates, the circuit is not conductive ( light off ); N.O. means Normally Open: When the magnet separates, the circuit is conductive( light on ); When the magnet together, the circuit is not conductive ( light off ). Please check the right need carefully before purchasing it!

### ⭐⭐⭐⭐⭐ Switches work!

### ⭐⭐⭐⭐ Working well at 3.3V logic level. One was high-resistance at first, but fixed by a hard drop
*by P***T on December 8, 2019*

I have several sets on 50-100' wire lengths back to an MCP23017 I/O expander chip at 3.3V, set to generate an IRQ on edge events. As with most switches, they were quite "bouncy" at first, but a 1uF cap across each (at the controller end) solved that Contact resistance was generally 3-6 ohm, which was fine, but one side of one of the switches (I can't remember if it was NO or NC side) was up over 600-800 ohms at first, varying slightly on every cycle, but never as bad as the one in Nancy's review. However, this "fixed" itself after I accidentally dropped it about 5' on to a concrete floor, and has operated reliably ever since! I used large enough pull-up resistors (22k?) on these sense lines to hopefully tolerate that level of contact resistance if it returns, but after 4 months, it's still under 10 ohms. The double-throw design of reed relays inside these could make intermittent marginal contact more likely. I'd have chosen NC-only (closed when magnet is present) if those were available for the same price. You really don't want to run any significant current or voltage across these. It may work at first, but contacts are unlikely to last very long in this role. Use a FET, etc. if needing to directly switch a load.
