How can you connect a lamp to the power supply in such way so that the the lamp may be turned on and off independently by any of the three switches?
By connecting the three switches in parallel.
What are the two conductors that connect 3 way switches together called?
The two wires that travel between two three way switches are called travelers.
How do you wire a 2 way light switch down stairs to a 1 way switch up stairs?
You don't. You use a pair of two-way switches ('three-way switches' in US/Canada).
How many 4 way switches could you put on a single light fixture?
If you are talking about intermediate switches, the switches that are in the middle of the three way (UK two way) circuit, then you can add as many as your project needs. These type of switches must be in the middle, as if installed on the end, the different position switching will not operate.
How is one light controlled by three switches?
That is called a 4 way light switch circuit. On each end of the circuit you install a 3way switch and in the middle you install a 4 way switch.Answer using British TerminologyIn the UK, 'three-way' switches are called 'two-way' switches (more logical, if you think about it!), and the 'four-way' switch is called an 'intermediate' switch.
What is the function of four way switch?
The use of a four way switch is needed when a load (such as a light) needs to be controlled from 3 locations or more. For instance when you walk down a hallway and there is a light there are probably at least two switches one at the beginning of the hallway and one at the end. These two switches will turn the light on or off from either location. These two switches will be three way switches. When the need to control a light or a load from more that two locations arises a four way switch is introduced. A light or load can be controlled an unlimited amount of locations by adding four way switches which are wired in between the two three way switches. Think of a sandwich where the three way switches are the bread and the meat and veggies are the four way switches. You can put as much meat and veggies as you want, but you always need two slices of bread on the top and bottom.
Why after installing three-way dimmer the multiple switches no longer work?
Was it installed in a three way or four way system?
How can you connect a lamp to the power supply in such way so that the the lamp may be turned on and off independently by any of the three switches?
By connecting the three switches in parallel.
Where can you buy 3 way switches in Pittsburgh?
There are several places that store three way switches for selling in PA. Some local ones are these: Kitchen Distributors of the North Hills, Sandfree, Kitchen Switch and Switch Three Way.
What are the two conductors that connect 3 way switches together called?
The two wires that travel between two three way switches are called travelers.
When a bulb is to be operated from three places what are the switch requirements?
I think there are more than one solution but the one I understand is to provide two by two way switches linked with two strap wires. A cross over switch is also used at some third location to 'cut' the straps, linking A to B and B to A alternately dependant on switch position.The commons are connected to live or load. I always need to draw a diagram for each pathway just to make sure.Clarification:The above answer is (semi) correct. You need two three way switches at the ends of the circuit, and one (or more) four way switches in the middle. The three way switches select between A and B for power, and the four way switches flip A for B and B for A. You can use any number of four way switches, making this an N-Way circuit. The three way switches are SPDT, and the four way switches are DPDT with an internal cross-over.
How can you control light from three places in a hall?
In UK parlance, you need to use a pair of two-way switches and an intermediate switch.In North-American parlance, you need to use a pair of three-way switches and a four-way switch.

Wire a three-way switch One light controlled by two switches- similar to a hall ligt. SPDT switches?
yes like a hall light.
A lamp is to be controlled independently by switches in two different locations?
It is called three way switching.
