Abstract
A downhole control system can include a pair of drive lines passing through a wellbore member such as a tubing hanger, and a plurality of hydraulic switches, each in communication with the drive lines. Each hydraulic switch can have a unique pressure band, wherein the switch only responds when the pressure in the drive lines is within the unique pressure band. Once the pressure in the drive lines is within the pressure band, the switch can open or close in response to a pressure differential in the drive lines.
