The common wire is located on a 3-way switch. If you have one then you can find it on either the hot wire or the switch leg. This is the wire running directly to the actual fixture, whether it be a light or a lamp or any other type of electrical switch for an appliance.
As far as the content of the remaining wires are concerned, they are described as travellers and are the wires that connect the switches together; these should be enclosed tightly and insulated accordingly.
If you need to wire your property then, unless you are an experienced electrician it is essential you call in the services of electrician professional in order to do the handy work. They will be able to know where the common wires are, what their usage and function is and how to handle them in a safe and controlled manner.
It is unadvisable to touch anything that you are unsure about as this could spell danger. For example, if you want to move light fittings, or you need your lounge completely rewired, this is a bigger job that needs the work of an electrician who will be able to move the electrics in a calm and safe manner. If you need outdoor security lights, again this needs careful work regarding your wiring system and has to involve your fuse box.
Above all, the common wire on a switch should only be inspected by a qualified electrician as you could cause yourself damage or even worse an electric shock which may cause you injury.
