Modern home life is inseparable from electricity, switches and sockets as electrical accessories often used in our daily life, its safety and durability is what we need to pay close attention to. The types of switches and sockets used in different equipment are also different. The switches and sockets involved in the family mainly include: common switches, power sockets, information sockets, panels, etc. We should choose the type of socket according to the actual situation. Only the installation of qualified switch and socket can ensure the convenience and safety of home electricity. What are the types of wall switch and socket? What are the internal structures of switch and socket? Let's learn from each other and take everyone to recognize them.

1、 What is switch socket

Switch and socket is the electrical switch and socket installed on the wall, which is used to connect and disconnect the circuit of household appliances, sometimes for the sake of beauty and make it have the function of decoration.

2、 Types of switch socket

1. Switch

The switch has the difference between double control and single control. Each unit of double control has one more terminal than that of single control. A lamp can be controlled in the room or outside the room, which is called double control. The double control switch can be used as single control, but the single control switch cannot be used as double control.

(1) According to the starting mode of switch: pull switch, rotary switch, flip switch, button switch, seesaw switch, touch switch, etc.

(2) According to the connection mode of the switch: single control switch, double control switch, bipolar (dual) double control switch, etc.

(3) According to the specifications and dimensions, the standard types are 86 (86mm × 86mm), 118 (118mm × 74mm) and 120 (120mm × 74mm).

(4) According to the function classification: one single (double) control, two single (double) control, three single (double) control, four single (double) control, acousto-optic control delay switch, touch delay switch, doorbell switch, speed regulation (dimming) switch, card access switch.

2. Socket

The narrow sense of wall switch refers to the switch, which actually refers to the large area of wall switch and wall socket. There are mechanical, intelligent, flat and seesaw.

(1) Computer socket is also called network socket, network cable socket, broadband socket and network panel. One kind of network is separated from the telephone, so there is a telephone computer integrated socket; the other kind of network is separated from the cable TV, so there is a television computer integrated socket.

(2) Telephone socket.

(3) TV socket is also called TV socket, TV panel and cable socket.

(4) Air conditioning socket, also known as 16A socket, because the general socket is 10A current, air conditioning socket is 16A current.

(4) 118 socket is horizontal rectangle, 120 socket is vertical rectangle, 86 socket is square. 118 sockets are generally divided into one, two, three and four sockets. 86 socket is generally five hole socket, or multiple five hole socket or one open with five hole socket.

(5) The weak current socket is a USB electronic product with about 5V output voltage.

3、 Internal structure of switch socket

(1) It is made of tin phosphor bronze, which is inserted and pulled tightly.

(2) The socket copper sheet is made of tin phosphor bronze, which has high strength, good plasticity, good conductivity and is not easy to deform.

(3) The design of electric shock protection door ensures the safety of children.

(4) All power outlets are equipped with protective doors to prevent children from electric shock.

(5) Add lightning protection function to protect life safety.

(6) Add lightning protection module, one more layer of protection, effectively reduce the damage to people and property caused by lightning and overvoltage.

(7) The structure design is unique, and the plug and pull coordination is accurate.

(8) Cylindrical plug and flat plug have special socket to ensure the stability of current.

(9) The icon and label card are easy to use.

(10) The icon and label card of the information socket can easily identify the use of the socket and the circuit, which is convenient for use and inspection.

(11) Long distance design, reduce the use of mutual interference.

(12) The distance between two and three holes can reach 42mm, and two large plugs can be inserted at the same time to improve the use efficiency.
