ABSTRACT:
A control system capable of selectively providing one of a plurality of control signals with each signal corresponding to a particular predesignated function. The output signals from the control system are generated in response to constant voltage input signals. The system includes an input circuit and a control circuit. The input circuit is coupled to the control circuit through a single transmission line over which a constant level voltage is transmitted. The voltage level of the input signal which is transmitted is selected from among a plurality of predetermined levels in dependence upon the control function to be achieved. The control circuit, in turn, receives the input signals and in response thereto will activate one of a plurality of switches for providing a corresponding output signal which serves to enable an appropriate control function.
