Daisy chaining is a method of connecting several light fixtures to a switching circuit in which the lights are connected in parallel and controlled by a single switch. Wiring four lights on one switch, often known as daisy chaining, is an effective technique to manage lighting in homes and businesses. Each new light added gets its own branch off the main wiring system with its own switch at the end of the chain. If any light in the chain is turned on, they all come on.
The first light in a chaining series is called the master control. It can be any type of fixture, such as a floor lamp or table lamp. The second unit in the series is called a slave unit. It must be a light bulb that fits into a socket designed for a 40-watt bulb. The third unit is called a secondary controller. This unit can be any type of light fixture such as a ceiling fan or chandelier. It can even be a motion-activated sensor if you want your garage door to open when it's dark out. Finally, the last unit is called a remote controller. This can be any type of light fixture such as a reading lamp or nightlight. It can also be a camera flash or gas fireplace igniter.
To wire four lights for daisy chaining, start with the master control located on the first floor.
This light switch wiring may be accomplished in one of two ways. The most typical method is to daisy-chain the light fixtures by joining them and connecting the first one to the switch. Another method for connecting several lights to a single switch is to link them all directly to the switch in a "home run" arrangement. This article will discuss both methods.
If you choose to chain several lights together, use a hot wire from each fixture to the next. Make sure that none of the wires inside the chaining system are joined together until they reach the fixture that will act as the last link in the chain. At this point, these wires should be connected to separate terminals within the fixture. If you connect them to the same terminal, there is no way to tell which one will be connected to the power source when you turn on the switch. This would mean that both lights would be on when only one was desired.
It's also important to note that if any of the wires inside the chaining system are not up to code for ground fault interrupting (GFI) outlets, then the entire chaining system would not be GFI protected. You must use GFI outlets or replace the wires inside the chaining system with dedicated conductors for each light.
If you decide to connect several lights to one switch using the "home run" configuration, all of the wires should be identical lengths.
The second approach allows you to simply detach fixtures that you no longer want to use, but it gets inconvenient when there are more than two fixtures involved. For example, if you connect the switches for the living room and dining room directly into each other, then removing merchandise from either room would also remove power from the other. This method isn't suitable for every situation, but it can be useful if you tend to switch things on and off frequently.
Multiway switching in building wiring refers to the connecting of two or more electrical switches to regulate an electrical load from more than one place. Lighting is a typical use, as it permits management of lamps from many places, such as a corridor, stairway, or big room. Switches are used instead of a single switch that can turn on several lights at once because some people find it difficult to turn off all the lights in a room by simply turning off one switch. Instead, they can leave one switch on and another one off to avoid having to go through this trouble.
There are two types of multiway switches: those with three wires that carry current to the lights not controlled by a single switch and those with four wires that carry current to both controlled and uncontrolled lights.
Three-wire switches connect either red to black or white to green to the load. They require only one circuit per assembly, so each additional switch adds to the complexity of the wiring. Four-wire switches are more complex but provide better lighting control because they can separate lights plugged into them with different methods. Loads must be connected differently depending on which side of the switch they are plugged into. The first side gets black to ground and white to center; the second side gets black to ground and red to center.
People often ask why multiway switches are needed.
Switching with several paths Two or more light switches can be linked together to control illumination from, say, the two ends of a long corridor or the upper and lower landings of a flight of steps. Special switches with extra contacts are used for multiway switching. The contacts may be normal metal screws attached to insulated boards, or they may be molded into plastic plugs that fit into standard wall outlets.
The first multistage push-pull switch was invented by Harvey Hubbell and introduced by General Electric in 1950. It used ceramic discs as contactors. In this type of switch, each stage has its own coil which is either "on" or "off". When activated by an electric signal, it sets into motion another coil in another part of the switch mechanism which in turn closes or opens the next stage. This process continues until all the stages have been turned on or off.
In order to save space, many modern office buildings use remote-controlled lighting systems operated by magnetic switches located near their power sources. These switches are usually mounted on the wall behind the desk or table where the lights are needed.
Remote controls can also be used with appliance type lights such as those found in kitchens and bathrooms. Such lights are controlled by magnets placed near the corresponding appliances (such as refrigerators or ovens) when you want them on, or outside their range when you don't.
Switches with three positions Three-way switches are frequently used to control a light fixture from two separate places. One person can turn on the light in a room while another turns it off. This is especially useful if you have children or pets who might want to use the light when you're not around.
Three-way switches are simple to install and operate. They usually have plastic or metal housings and come in either single-pole or dual-pole configurations. Single-pole switches require both terminals to be connected together to turn the power on/off. Dual-pole switches have separate terminals for hot and cold wires. The technician must determine which terminal of the switch controls which side of the circuit before making any connections. After making the necessary repairs, the technician must test each terminal of the switch to make sure that it still works before connecting it to its corresponding wire.
If you are having difficulty turning your lights on or off, check to make sure all the wiring to the switch is intact and the switch itself is not damaged. Wires may be broken or disconnected at the wall plate covering the opening into which you inserted the body of the switch. If so, replace the wall plate before attempting to fix the problem.
