In this you use 2 single pole double throw switches and a double pole single throw switch. Agian try to ignore the dots.

The standard home center names for the switches are "two way", "Three way" and "four way" switches. Two way switches are used when only one switch will control the device, three ways are used in pairs and four ways are used between three ways to get more than two switches in a circuit. You should be able to find all three types at you local home center. The four way are typically more pricey because they are less common. The circuit above has two three way switches and one four way switch. For the three way make sure you identify the "common" terminal when wiring. On the four way you need to identify the pairs (look for a diagram on the box or the switch back).
Hope this helps!
Good LucK!
