Specification GB50259-96 Switches installed in the same building or structure should use the same series of products, and the on-off position of the switch should be consistent, and the operation should be flexible and reliable. The position of the switch installation needs to be easy to operate, the distance between the edge of the switch and the door frame is generally, if there are no special requirements, the height of the bottom of the lever switch from the ground is generally.
The four sides of the switch and socket must be tightly attached to the wall, and the entire switch and socket is in a flat plane, and there can be no warping edges and corners. In addition, shake the switch socket, there can be no looseness - if it is loose, it proves that there is a problem with the fixing nut of the junction box, which is easy to fall off when used in the future, and it is very difficult to maintain. At this time, the renovation personnel should be asked to carry out repairs immediately to avoid future troubles.

Anonymous users2024-01-22This clause is from: Code for Construction and Acceptance of Electrical Lighting Installations in Electrical Installation Engineering GB 50259-96 Phase wires shall be controlled by switches; It is strictly forbidden to install bedside switches in residential buildings. This was a regulation from '96, when most bedside switches were cord switches, not the current dark switches.
In addition, according to the requirements of GB 50303-2002 version of the Code for Acceptance of Construction Quality of Building Electrical Engineering: there is no bedside switch for civil residences with soft wires leading to the bedside.
Therefore, it can be basically determined that the former requirement is strictly forbidden to install the bedside switch with a soft wire leading to the bedside. This kind of flexible wire is very easy to cause electrical fire and electric shock risk, so the state prohibits it.
However, the current ones are all dark switches, so the standards are a bit outdated. Therefore, the standard of "Code for Construction and Acceptance of Electrical Lighting Devices for Electrical Installation Engineering" has been abolished, and the standard that replaces it is the "Code for Acceptance of Construction Quality of Building Electrical Engineering". The latest version is GB 50303-2015.
In this version, there are no longer any requirements for the bedside switch. Please familiarize.
