I have a light switch in my garage that controls the attic light. I want to change that switch to a combination switch/outlet. I have 3 sets of 3 wires coming from the box in the wall. In the upper left hand corner there is a black, white, and copper wire. In the upper right hand corner. there are two diffrent set of wires both have a black, white and copper wire.

The way the switch is hooked up now all white wires are twisted together with with a wire cap, all copper wires are twisted together with a wire cap. black wire from left side and one black wire from right side twisted together with feeder wire this wire is in top hole of switch. Last black wire is in bottom hole of switch.

My question is can I use these wires to install the combination switch/outlet. If so how do I do this with available wires.

I do not want the swith that will turns the attic light on to be on for the outlet to work. Can I achieve this goal with the wires I have. Please Help

 

Yes you can replace the switch with a combo unit.
Connect the black pigtail from the switch to the double brass screw on the new unit.
Connect a new pigtail from the white wires to the silver screw on the outlet.
Connect the single black wire from the switch to the single brass screw.
