Optical isolation uses an LED (Light Emitting Device) and a photosensitive transistor to transfer data across the isolation barrier - typically an air gap; in other words, data is transmitted using light instead of electrical signals, so there is no physical connections between the grounds and the data lines, thus removing the ground loop problems and effectively preventing electrical surges and spikes from destroying other parts of the system.
Thank you so much for helping, I found where the main power comes from and it's hooked to the GFI that's next to the switch, so I did a pigtail of the (hot) black wire to the switch and then the other black wire that runs from the outlet from underneath the sink to the other bronze screw on the switch.
