[0002] The easy-to-install magnetic door switch for washing machines is a specially designed sensor used to detect the open and closed status of the washing machine door. This type of magnetic door switch usually consists of two parts: a permanent magnet and a door magnet body. The permanent magnet is a smaller part that contains a permanent magnet inside to generate a constant magnetic field. The door magnet body is the larger part that contains a normally open reed switch inside.
[0003] According to Chinese patent publication CN202220416691.3, in this application, the long U-shaped through slot can be used to easily adjust the locking bolt, thereby adjusting the overall position and improving the installation accuracy.
