how to wire two switches to one light

To control a single light from two locations it is necessary to have two, three way switches wired together to switch the light. You will need 12/3 with ground romex running between the switches. The bare copper ground wire is not shown in this diagram but it would connect to the green screw on the switch.

with a little more info .. is the light fixture closer to one switch? is there only one light to be controlled .. is this new construction, open walls??


The light can be wired from either switch, or between the switches .. one of the three possibilities might fit this situation better ..
