Switches and sockets in distribution ready board

Although switches and sockets are not "big items" like household appliances, they look like small things, but they are related to the daily "big safety" of the family. Many people do not pay attention to their choices and think that as long as they can control them, they can. In fact, there are also many articles on switches. Then, how to select the switch socket in the distribution ready board?

The price difference of switch socket mainly lies in the use of materials, internal structure and appearance design. You get what you pay for. Products with low prices are usually discounted in terms of materials, handling and durability. The simplest selection method is "one listen, two smell, three heft". Listen: listen to whether the sound is clear and smooth after the key on the switch panel is pressed; Smell: whether the materials used have peculiar smell; Dian: look at the weight. Usually, the weight of good shell insulation materials, high-quality contacts and current carrying copper sheets should be heavier.

Pay attention to the following when installing switch socket in distribution ready board:

● check whether the appearance surface of the switch socket is smooth and rough, and whether there are bubbles or depressions.

● the terminal shall be bright without rust marks.

● when wiring, screw the screw without blocking feeling, and it will not loosen after tightening.

● the switch socket shall be flat without inclination after being installed in the distribution ready board.

● the opening and closing of the switch shall be clearly marked.

● the switch feels light, the sound is clear, and the response is sensitive. The socket is equipped with a protective door, which can be plugged in and out smoothly. It feels a little tight when plugged in.

● 16A socket shall be selected for air conditioner. General household plugs and sockets are 10A. 10A has a maximum capacity of 2200W and 16A has a maximum capacity of 3520w. When selecting a socket, you can look at the current and voltage signs on the plug of household appliances. If it is a plug less than 10a, you can buy a 10A socket. If it is a plug greater than 10a, you can buy a 16A socket.

Silver nickel alloy has strong conductivity and hardness, and is not easy to wear and oxidize. Good comprehensive performance, easy to generate arc

Silver cadmium alloy. However, cadmium is a heavy metal, which is harmful to human body. At the same time, its fusion with silver is not ideal. It will form small cadmium particles on the surface of electric shock, and may pull out an arc when conducting electricity.

Pure silver has good conductivity, but it is easy to oxidize, soft, easy to deform and easy to produce
