I attatched a photo of a switch that I have no idea which wires go where. If someone would please help me tell me how I would appreciate it.
you might want to have two switches in the same wall box-- BUT . you only mention that you have three wires to deal with . WALL SWITCHES are designed to break or cut the power to a ceiling light or a fan/light device the switch gets two black wires [[[ those blk wires indicate the switch LEGS as they are called by the electrical tradesmen ]]] the 12/2 romex with the ground goes directly from the electric panel breaker to the overhead light and the black wire is cut and the switch legs are then down inside the wall to the light switch I am not familiar with the connector box thingie you have in the photo so I am not addressing that photo AND it is my opinion that you should buy some books and do some reading to learn more about electrical wiring and the safety .
I would think that the wires go just exactly where they are attached to. Without additional information about what this switch is FOR, there is no way to tell anything more.
