Weight and texture
The genuine bull socket has a certain weight, while the general fake bull switch socket is very light in your hand and has no texture at all.
Insulation-proof and high-temperature resistant material
Bull switch socket is made of insulation-proof and high-temperature resistant materials, while most counterfeit ones are made of organic plastics. We just need to bake it on the surface with a lighter. If the surface turns black, it means they are fakes. The black stain on the surface of the real cow socket will disappear after wiping.
The copper sheet is made of phosphor bronze.
The copper sheet inside the bull socket is made of phosphor bronze, which has good conductivity and durability. When shopping, we can try to plug in an electrical appliance to see if it is compact and the plug is easy to loosen.
Anti-counterfeiting identification
We can also check whether it has the corresponding anti-counterfeiting mark when we buy it, and we can know whether it is true or not by checking the code on official website or the official telephone.
