How to connect the switch wire, how to connect the switch wire

1. How to connect the two wires to the switch.

1. These two wires are generally one is the live wire and the other is the zero line, and we need to distinguish them first.

The live wire should be connected directly to one end of the switch, and generally on the jack on the left, while the neutral wire should be connected to the other end, generally on the jack on the right.

Because there are only two wires, there is no ground wire, and the jack in the middle does not need to be connected.

2. Two wire switches, in fact, is to use a switch to control a lamp, when we wiring, we should connect one of the wires to the terminal post in the middle of the switch, and the other one should be connected to any one of the binding posts.

3. If it is a three-hole socket, then the two wires should be connected with the neutral wire and the live wire on the socket respectively, and there will be signs on them, and we just need to distinguish them. The ground wire on the socket, that is, the yellow and green wire, can be left unconnected.

Second, the two wire switches, what aspects need to be paid attention to.

1. Before wiring, because there are live wires, neutral wires and ground wires, it can be easily wired when distinguished, we can distinguish them according to the color, and we can also use other ways.

2. When wiring, it is also necessary to follow the principle of left zero, right fire and middle ground.

3. At the same time of wiring, we also need to choose a matching wire to connect with the electrical appliance, so as to avoid the fire caused by the short circuit of the wire in the future, or the wire can not withstand too high current, resulting in too high load, and the wire aging in advance, there are potential safety hazards.

3. How to distinguish between the live line and the neutral line.

1. Directly according to the color, generally speaking, the red is the live line, the blue is the neutral line, and the yellow and green is the ground line.

2. Use a voltage tester.

It is the most straightforward and safest method. If there is voltage near the wire, and the pen makes a sound, it is a live wire. If you get close to a line where there is no voltage, the pen will not make any sound, and it proves to be a neutral line.

The switch wiring needs to be disconnected from the power supply first, and then the rubber at both ends of the wire is removed with pliers to expose the copper wire. Then connect two wires to the two holes of the switch, one wire is connected to the lamp, and the other is connected to the power live wire. Finally, use a wire to connect the neutral line of the power supply to the lamp, fix the wire, and turn on the power supply. ”

Summary. Hello dear, happy to answer your <>

The wire method for connecting the switch is to remove the rubber on the front head of the wire to be connected to the switch with pliers, so that the copper wire that can conduct electricity is exposed. The copper wire part that can be conducted by the two wires just processed is connected to the two terminal holes of the switch, and then the other end of the two wires is connected to the power supply and the lamp respectively. 3.

Next, use a wire to connect the power supply to the light to form a circuit

Kiss switch refers to an electronic component that can make the circuit open, interrupt the current or make it flow to other circuits, circuit breaker refers to the switchgear that can close, carry and break the current under normal or abnormal circuit conditions, the circuit breaker can be used to distribute electric energy, start the asynchronous motor infrequently, protect the power supply line and the motor, the circuit breaker is divided into high-voltage circuit breaker and low-voltage circuit breaker according to its scope of use. Switch can be divided into A-type contact, B-type contact and C-type contact according to the contact type, the switch control system can easily realize the switch state control through a variety of signals such as radio waves, and the switch mechanism is a mechanical device that makes the contact complete the breaking and connecting circuit according to the specified requirements in the high and low voltage switch

How to connect the wires to this.

Hello, dear, the method of switching wires is as follows, first of all, we need to understand the commonly used wire color, in general, red, yellow, green wire is used as phase wire, that is, the live wire is often represented by L; Blue is used as a neutral line and is represented by n, and yellow-green is used as a ground wire.

2. The connection method of single-open 5-hole socket: single-open 5-hole is generally divided into switch part and socket part, but these two parts are combined. This kind of switch socket has 5 binding posts, let's first distinguish the purpose of each binding post.

First connect the ground wire to the ground wire binding post, then connect the power access line to the L of the socket, and add a wire to the power access line L of the switch simultaneously, in this way, the power supply of the switch and the socket is connected.

3. Of course, to power the socket, we also need to connect the neutral line to form a closed loop, so we connect the neutral wire to N. Finally, to light up, we also have to connect the lighting control line to L1, so that when we press the switch, the power will be turned on, and the light will be on. 4. Connection method of double-open or triple-open lighting switch:

Double-open open-and-find switches generally have three or four binding posts. We first have to open the design of the switch, some of the power access lines of the two switches have been connected together, and some have not, the reason is the same. First of all, distinguish the purpose of the binding post:

Generally, a lamp has a control line L1, a double open is 2 L1, a triple open is 3 L1, a power access line L, and no connection is 2 L.

You belong to it, and you open a single control.

The wiring method is as follows, the L of the switch is connected with the power live wire, and the L1 of the switch can be connected with the control wire of the controlled electrical appliance (lamp). How to wire the surface-mounted switch first turn off the total power, open the panel with a tool, and then connect it according to the components: there will be two holes for single control, then the live wire is wound around the L hole, and the other is wound around the L1 hole with the light wire.

For dual control, first wrap the live wire to the hole marked L1 and L2, then wind the light wire to L1A and L1B, and finally the wire to L2A and L2B. One switch controls one light, and the wiring is relatively simple. The L hole of the switch is a common termination live wire, and the hole is connected to the control wire of the lamp.

If you take the order control, there is no requirement for the control direction of the switch, L1L2 two holes can be connected to one at will.

There are L, L1 and L2 wiring methods on the switch: live wire access method, five-hole socket connection method, and double-open access method.

1. If it is a single control switch, L as the common end, you need to connect to the live wire, and L1 and L2 as the control line, we only need to connect the live wire from the L terminal end, and then connect from L, and choose to connect one from any hole of L1 or L2.

2. If it is an ordinary light switch, generally speaking, the five-hole socket is chosen, it is the part with the switch, and the part with the socket, so the two are together. This kind of switch socket generally has 5 binding posts, first of all, you need to understand the purpose of each binding post, there is an access line marked with L, it is used to connect the live wire.

3. If you want to use double or triple open, generally speaking, the switch has 3 or 4 binding posts. We need to connect one of the wires, each to the lighting control line, the wiring port of L1, and finally add a wire, and connect the two L's together.

How to connect the switch with a socket is safer

1. Clean the socket bottom box.

Before wiring, first of all, clean up the dust and debris in the socket bottom box, and keep it dry, so as to avoid affecting the electricity consumption. If there is still moisture in the socket, the wire is prone to electric shock, short circuit and other accidents after connection, which is easy to cause safety accidents.

2. Dispose of the power cord.

When wiring, an extra section of wire should be set aside, so as to facilitate later maintenance. When trimming this excess wire, cut off the excess core, but do not damage the core inside it when cutting, so as not to damage the wire.

3. Wiring correctly.

When wiring, it is necessary to standardize the operation of the loose work, the live wire, the neutral line, etc. should be correctly connected with the socket, if the wire is reversed, it is easy to cause safety accidents. When wiring, the wires need to be firmly connected. When the wires are connected, you need to check whether the wires are connected correctly, and if you find that the connection bureau is reversed, you need to reconnect to avoid safety accidents.
