1, the sound is generally caused by poor contact, if it is found that the contact between the plug and the socket is poor, or the switch is in poor contact, it will produce a large current, and the internal spark will be generated. With the sizzling sound, it will burn the copper sheet black. If the quality of the socket is slightly poor, it will burn out, which will cause a fire.
2, so if you hear a sizzling sound, you must pay attention to it, and you need to check to ensure that there is no problem with contact. If the socket has been burned out, to replace the new socket in time, choose a slightly better quality.

3, socket use time is too long, if the internal copper deformation or fall off, or no elasticity, there will be sound, in this case we can use pliers to reset the copper, adjust to the best state. If you can't replace it directly, don't give up.
4, if some copper sheet loses elasticity, or the screw is not fixed, as long as the screw can be re-tightened, but if there is no elasticity, it is recommended to replace the new socket directly to prevent the occurrence of short circuit safety hazards.

Second, how to choose the household socket
1, the most important thing in the socket is its copper, so we should pay attention to the choice of copper. The better copper sheet, the color is relatively bright, the surface is relatively smooth, and this quality is slightly better.
2, to look for the 3c certification mark, the choice is copper material, the hardness will be greater, the service life will be longer. We need to buy some regular brands, as well as better after-sales protection.
3, when buying, you can weigh it in your hand, the quality is better, its material is more sufficient, slightly heavier, and we can plug it, the plug is better, and the connection is more firm.
