Swtich wiring
#1

I have a switch out in my dining room. I bought a new switch but the old one has three wires plus a ground. Two of the wires are punched in and the third is connected by the bolts to the top. Could this third one be for a ceiling fan? Can I just bolt it off?

Switch:
If the switch is a single pole, and not a three way. It sounds as if they used the side post as a termination point for functioning two wires together. If this is the case then wire nut the two wires together. Then install a jumper wire from that wire nut that will feed the switch with just one wire, then connect the other wire to your switch.

khutchins, as aphares said, this is a very common way of using the switch to connect two wires (the backstabbed wire and the wire on the screw adjacent to it). You would almost certainly lose power to some receptacles or other lights if you were simply to cap it off.
