Netizens share: nanny-level switch socket knowledge, common sense of switch socket installation!
Switch sockets are definitely indispensable during home decoration. In order to avoid detours when buying and installing switch sockets, and to buy more suitable products, it is necessary to learn some knowledge about switch sockets before decoration. Let's take a look at the nanny-level switch socket knowledge summarized by these enthusiastic netizens with "Future Home Improvement Network", let us avoid detours when choosing switches, and master some basic switch socket installation knowledge!
1. Switch selection
Switch selection should follow three principles: safety, beauty and convenience.
Switches are divided into single-open, double-open, three-open and four-open. Four-open is not very common. Electricians are used to using two sets of double-open instead of four-open. Each switch with different numbers is divided into single control and double control (the number of terminals on the back is different), and single control is cheaper.
Commonly used are blank panels, telephone sockets and network cable sockets-TV sockets have been eliminated in the past two years, and the remaining rotary switches and the like are relatively used less.
2. Types of switches
1. Single billing control
The connection method of single billing control is as difficult as the socket connection, or even simpler. It only needs to connect a live wire L and a light wire (from the neutral wire). It is usually used in a single entrance position such as a bathroom or a kitchen.
2. Single open and dual control
The two single-on and dual-control switches can switch between the two wires continuously to realize the on/off of the same lamp. Dual-control switches are mostly used in corridors/stairs with multiple entrances, or at the door of the room and the bedside.
3. Double open and double control
Dual-open dual-control is an advanced version of single-open dual-control. The only difference is that there is a set of (three) terminals side by side, and the naming of the terminals has been changed: L1 and L2 are used to distinguish two different fire wires; The original L1 and L2 have become L11 and L12 and L21 and L22 respectively.
If it is determined that both switches are single-controllers, based on the principle of saving money, you can purchase a dual-opening single-control switch; but if one dual-control, one single-control, you need to purchase a dual-opening dual-control switch.
Three, socket wiring
The wiring logic of the socket is simple, that is, a blue neutral wire N, a red live wire L, and a yellow-green ground wire. When using external electrical appliances, short-circuit the neutral wire and the live wire through the plug to obtain electricity.
If there are 5 jumpers on the back of a socket, two wires are connected in the neutral and live holes respectively, and the extra wires are connected to the neutral and live positions, usually a nearby switch/socket to connect Jumper wire used to get power from this socket.
4. Summary of experience
Although the default is red live wire, blue zero wire, yellow light wire, and yellow-green phase indirectly.
Although the electrical appliances can be used normally when the socket is interchanged between the left and right sides, please follow the basic wiring rules of "left zero fire right" to reduce any possible hidden dangers.
In the replacement operation, the operation must be standardized, and the main switch should be cut off before the operation. Do not operate with electricity, just in case.
If you are working with electricity, do not directly touch the previously confirmed neutral wire and lamp wire with your hands. You never know whether the same neutral wire will be connected to other neutral wires, and you do not know whether other neutral wires are charged due to leakage. .
It is best to prepare a flat-blade screwdriver before the operation to pry the panel; a Phillips screwdriver to screw the screws; an electric pen to confirm the circuit (not available); a needle-nose pliers to assist operation. All of the above four tools are the best, but there is no one. Only a Phillips screwdriver can handle it.
