1.Take off the outer frame of the switch and receptacle and pinch it with your hands. If it does not break, it means that it is a better PC material. Such a material has better insulation and anti-aging properties. The intuitive feeling is that this material will not turn yellow in the future
2. To fix the switch socket to the wall, it needs to be screwed to its base. The firmness of the base will also affect the use of the switch panel. Now some brands use cold-rolled steel plates to make the base, which will be more durable.
3. The quality of the module of the electrical socket is the most critical, and it is difficult to distinguish it from the naked eye. In fact, we can judge by some details. First of all, the heavier the quality, the better the quality. In addition, there are screws behind the switch socket to fix the wire head, The good ones should be pure copper, and are larger ones., and the electrical metal stamping parts of some switch sockets are copper-plated or small, which means that their quality is not very good.
4. The socket should be purchased with safety protection. There are baffles in its jack. It needs two holes to be inserted together to insert it. You can find an iron plate and try it. Insert one hole alone, it should not be inserted.
