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.

Note: Door magnetic induction can only provide a switch signal to the device, which can not directly load the power, nor directly connect the lamp!
