There are a bunch of ways to handle this—for example, you can assign each switch a power-of-two value based on their index in the tableview's data source, and then add the ones that are on together; this will give you a separate number for each possible combination, which you can then use as the name of the corresponding image (0.png, 1.png … 255.png).
