Yes you can hook up as many as seems fit to turn on and off fixtures from many locations. Just keep in mind the three way switches have to start and finish the combinations to keep the circuitry legal. No switching neutrals There are other systems that switch the neutral wire which in North America is against electrical code rules.
The switch operates from two locations, such as upstairs and downstairs, but there are three ways it can be set: both switches "on", both switches "off", or one switch "on" and one switch "off".
to wire a lamp to be controlled from three places you need two three way switches and one four way switch. the two traveller wires that would normally run between the two three way switches must be connected to the terminals of the four way switch
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.
You don't. You use a pair of two-way switches ('three-way switches' in US/Canada).
yes like a hall light.

After the building catches on fire.

I'm not sure but i think all switches 2xxx (2960) are layer 2 switches
Yes. Just connect one switch strait into the router. Then hook the other three switches into the first switch. -DJ Craig

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.
it means between the one eye switch and the 3 eye switches lies the key hidden in the sand
You don't. You use a pair of two-way switches ('three-way switches' in US/Canada).
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.
A three way switch is a switch that is used in a lighting circuit that allows the light fixture to be turned on from three separate locations within the building. In electrical terminology this switch is also referred to as a SPST, Single Pole Single Throw switch. The switch has three individual terminals of which two are always connected. These switches are usually located at the far extremes of the circuit with an intermediate switch between them. This intermediate switch is referred to an a four way switch.
