Although switches and sockets are not the main materials in the decoration, wise choices can not only add a lot to your home, but also protect the safety of you and your family and family property. The quality of switch sockets is largely determined by the copper inside.
1, in the same material under the circumstances to see the length of copper, the longer the better (because the copper length determines the size of the socket distance, the wider the jack spacing two or three insert at the same time more convenient to insert). The length of the copper below is fairly good, and some copper pieces are less than 4.5 cm in length.
2. The thicker the thickness of the copper sheet, the better. (The longer the socket life, the better the elasticity of the copper sheet.)
3, to see if the copper sheet is not formed into a piece of copper (you can clearly see the following picture of the entire block of copper material is exactly the same, without any riveting points).
Old-fashioned riveted copper sheets (obviously, it can be seen that the two materials are completely different from the bridge materials, and there are obvious riveting points). One-time molding is always better than the old riveted copper sheet, because the once-formed copper sheet is always smaller than the riveted resistance, the relative heat is smaller, the elasticity is better, the higher the safety factor is, the higher the conductivity is). The wires in the house renovation line are the same, the difference between a complete wire and a knotted wire.
4. Look at the size of the rocker contacts. The bigger the contacts, the better (in red circles in the figure).
