## Description

Package Content 1 × Magnetic 1 × Sensor Switch 4 × Screw Type - Normally Closed Our door reed switches are NC. Please kindly know before ordering. NC means Normally Closed:When the magnet together, the circuit is conductive( light on ); when the magnet separate, the circuit is not conductive ( light off ). Door Magnetic Installation Instructions The Door and window magnets should be installed at the door and the top of the window. The permanent 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 and installed as much as possible. Otherwise deviation from the best conduction area of the magnetic field line and the reed switch contact will shorten the sensing distance. If the misplacement is severely installed, the switch will not sense the attraction of the magnetic field and cause the switch to malfunction. It is recommended to position the pen before drilling. The door magnet should be away from the string magnetic field interference source such as transformer. Otherwise, the working characteristics of the door magnet will be changed and possible wrong actions may occur.

Review: 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!
Review: 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.
