An easily modified, brilliantly backlit, switch controlled panel graphically represents a process. An operator panel includes a frame holding a light-transmitting screen in front of circuit boards connected to a computer and to the controlled process. The screen displays symbols, placed on the screen with self-sticking tape, representing process steps and controls, transparent touch-sensitive switches, lights, illuminated digital displays, and the like. The switches, lights and displays connect to the circuit boards.
