Technical Specifications Product Name : Magnetic DoorContactReed Switch Material: Anti-fire ABS shield,Color: White 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. 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! 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 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.

Review: Simple and versatile, work extremely well - Configurable for normally open or closed. Quality. Great value. Eliminates guesswork. Perfect setup for me for low voltage closet lighting.
Review: Works great, nice packaging. - I like that they came in a clear plastic box that made it easy to store unused ones. I used them to trigger LED cabinet lighting and they worked perfectly. Having the ability to wire NO or NC is a great benefit that not all connectors like this offer. I will order these again for my next project.

### ⭐⭐⭐⭐⭐ Works great, nice packaging.
*by J***E on October 2, 2019*

### ⭐⭐⭐⭐⭐ The 'normal' position is with the magnet PRESENT.
*by S***S on October 10, 2022*

There are several reviews claiming these are labeled wrong, but these are labeled correctly for a magnetic switch! The 'Normal' position for a magnetic switch is with the magnet PRESENT, so when the magnet is present, the NC contacts will be closed, and the NO contacts will be open. Most 2 wire magnet switches are NC, and used with alarms, so that when a door or window is opened and the magnet moves away, the circuit opens, and triggers the alarm. This makes sense because it means if someone cuts the wires, the alarm will trigger. If you want to use these to turn on a low voltage light when the magnet is not present, you will use the NO contacts.
