About this item

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.
