The switch socket is used to connect and disconnect the electrical circuit. In order to use electricity safely, we must know how to distinguish between good and bad when purchasing the switch socket. Today, GELAN tells everyone how to distinguish switch sockets?
There are two ways to distinguish between switch sockets:
1. The contact, the so-called contact, is the contact point of the conductive part during the switching process. One depends on the size of the contacts, generally the bigger the better. Second, depending on the material, there are currently three main types of contacts: silver-nickel alloy, silver-cadmium alloy and sterling silver.
2, shrapnel, shrapnel is a key component of the switch socket, the main material is copper, mainly brass, copper and so on. Brass is easy to rust, the texture is soft, and the contact time will be long and the conductivity will decrease. If the color of the copper piece is purple, it is better. The copper is relatively tough and does not rust easily.
掂 weight. If it is a thin piece of copper, it will not have the same weight and quality. Only the copper piece and the terminal block inside the switch socket are thick, the weight of the single switch socket will be heavy, and the copper part inside is the most critical part of the switch socket, and it is also the key part of the fake and inferior products to cut corners.
The above is the identification method of the switch socket, I hope to help you buy the switch socket. If you want to know more about switch sockets, please continue to pay attention to GELAN electrical official website, if you have any questions, you can consult online customer service.
