Switches are commonly used decorative materials in home improvement, but many people do not understand its installation. Although the switch looks very small, if it is improperly installed, it may cause fire and electric shock. It is very unsafe. Many friends do not understand whether the light switch is connected to the neutral or live wire . Others think that the switch must be connected to the neutral or live wire. This is not the case. This is a misunderstanding. In fact, the switch is connected between the light bulb and the fire wire, not between the neutral wire and the light bulb. So today I will explain to you about the connection of the light switch to the neutral or live wire and the wall switch power supply wiring precautions.
Light switch connected to the zero line or FireWire
1. The installation of the switch must be correct. After all, it is related to electricity safety. If it is not properly installed, it will cause switch leakage and cause electric shock. When the switch is on the hot line, the on-off of the fire line can be controlled, and when the appliance is inspected, it can be ensured that the appliance is not energized.
2. It is understood that the switch controlling the lamp should be connected between the fire line and the bulb. When the switch is disconnected, the circuit not only has no current through it, and the lamp is disconnected from the fire line to prevent people from touching the lamp and the fire line to form a pathway, resulting in electric shock accidents. .
Switch installation considerations
1, pay attention to the switch socket installation position. The placement of the switch must be determined according to the family members' lifestyle. Today, most people are accustomed to using their right hand, so the door opens to the right, and the switch is mounted on the left side of the door. In addition, for the two floors of the staircase, dual control switches are used on both sides of the living room.
2, sofa wall, balcony and other reserved cable interface. When determining the quantity, consider as comprehensively as possible and use sockets for equipment. More than reserved socket is not enough for the appearance.
3, pay attention to switch socket waterproof and moisture. The sockets installed in the bathroom shall be provided with switches and indicator lights. If they are installed in wet locations, the surface shall be provided with a waterproof cover to prevent water vapor from entering the sockets and causing a short circuit.
4. Connection of multiple switches: When connecting multiple switches, there must be a logic standard, or in the order of the lights. Secondly, the exhaust switch of the kitchen must be connected to the multi-connector switch. Put it one after the other. The switch of the control light should not be opened. This function is separated, and it is easy to remember when it is opened later. Otherwise, in order to find this light, turn all the switches on.
5, can set up some with a switch socket, do not have to pull the plug can cut off the power, it will not affect the appearance, such as: washing machine socket can be closed when not in use, when the air conditioning outlet off the off-season;
Wall switch power wiring considerations
As we all know, household electricity generally has a live wire, a neutral wire and a ground wire before it is safe, and a ground wire is a yellow-green two-color wire. When wiring, first use a test pencil to find out the fire and the zero line, and mark it with color.
a. The wall switch is used to control the socket power supply. Connection method: firstly connect the wire to the L terminal of the switch, and then connect the L1 terminal of the switch with the L terminal of the two-hole socket, and then insert the neutral wire into the socket N terminal block on it.
b. The socket does not require switch control, but controls the lamp. The wiring method is: connect the fire wire to the L terminal of the switch, connect the L1 terminal of the switch to one terminal of the lamp cap, and connect the neutral wire to the other terminal of the lamp cap. Terminals, switches and lights form a loop. Then connect the fire wire to the L terminal of the two-hole socket, and insert the neutral wire into the N terminal of the socket. The two-hole socket becomes another loop.
Editor's summary: The above is a brief introduction of the experience of light switch users connected to the zero line or FireWire and the knowledge exchange of experience, hope to help friends who have this need!
