Switches are usually connected to digital inputs with one wire as well. The other wire is connected to either power or ground. The wire to the microcontroller is either pulled up or down with a resistor to power or ground, respecively.
My lab placed fancy touch-screens in the place of the light switches. Now turning the lights on or off takes at least 15 seconds but we get to pretend to be luxurious :(
