The control device is used to control delivery of fluids from a multi-fluid delivery system during a medical injection procedure. The fluid delivery system includes an injector used to deliver injection fluids to a patient. The control device is operatively associated with the injector for controlling discrete flow rates of injection fluids delivered to the patient. The control device includes a housing, first and second actuators associated with the housing, and an electronic substrate disposed within the housing and having a conductive pattern. The first actuator is operatively associated with the conductive pattern. The conductive pattern includes a plurality of predetermined digital values corresponding to discrete flow rates of injection fluids to be delivered by the injector. The second actuator is operatively associated with the electronic substrate and initiates output signals to the injector corresponding to desired mixture ratios of the injection fluids to be delivered by the injector.
