I have a light switch inside garage that powers a backyard light which I occasionally use. Inside that box there are 2 black wires, one hot and the other is not. There are also 2 white wires, and 1 ground Copper wire.
I bought a combination switch in order to add an outlet to that switch to use because it's kind of close to an exit door. Combination switch has 1 common black screw with a fin bridge to another black screw that's not labeled. On the other side, there's one brass screw with A1 written next to it. On the same side there's a silver colored screw with N written next to it. On the bottom there is a green screw which I know goes for the ground wire.
Now, how do I attach the combination switch with those different white and black wires. I'd like for the light switch to be separate from the power outlet. Thanks.
