[Shop-talk] Extra post....

[Jim Franklin]

That's a 3 way switch, for controlling a light form two places, like either end of a hallway. It needs another 3 way swicth, plus 14/3 wire between them, to work. If you're replacing a regular, one location swicth myou need to return this and get the correct one with 2 posts.
