Three-way switches require a three-wire cable: the power wire, the neutral wire, and the traveller or switch wire. The cable should also have a ground wire, or a total of four wires in the cable. The system also requires three-way switches. The switches are wider than regular single-pole switches and they have three terminal screws on the side sometimes back of the switch housing. Two terminals will be on one side of the switch housing; one terminal on the other side. Four-way switches have four terminals.

How to Wire a 3 Way Light Switch (with Pictures) - wikiHow
A three-way wall switch is a common type of light switch that makes it possible to control a ceiling light or other electrical fixture from two different locations in a room. Three-way switches are always used in pairs and include special wiring connections. The three-way switch is a variation of the standard single-pole switch, which controls a light only from one location. This configuration may be used in open-plan homes or in large kitchens or great rooms, where a central bank of lighting fixtures might be controlled from more than two entry points. If you examine a three-way switch , you will notice several differences when compared to standard single-pole switches. First, the body of the switch will be thicker and bulkier than that of a single-pole switch.
