Switch terminations depend on the switch. They come in a variety of configurations. We would need to know what switch you are using to definitively answer your question. Generally speaking, a rocker switch with 3 prongs would be a single pole double throw (SPDT) switch with the center contact being the common. Again, this would be the general configuration and may not apply to your switch. Some switches have markings beside the terminals to reference connectivity or a diagram on the side of the housing indicating how the switch is manufactured for electrical termination reference.
