To permit multiple use of data entry keys, and to effect different circuit connections by a single key, operation of any one of the keys is associated with time slots, or time windows so that, upon operation of anyone of the keys, a course, or sequence of time slots at intervals is initiated, each interval or time slot being temporally associated with a specific circuit connection. The length of the time course, that is, the number of time slots or time intervals is selected by continued operation of anyone of the control buttons, this continuance of operation or operating of another button, entering the then pertaining circuit into the system. An indicator is provided, continuously indicating the then pertaining time slot, and an additional indicator providing a symbolic output representative of the finally established circuit connection. The system may be used with a graphic display, such as a pointer pencil and a screen, the circuit connections establishing representation, sequentially, of electrical components which sequentially appear on the screen at the location indicated by the pointer so that, upon removal of the pointer, the then indicated symbol will persist on the screen, thereby permitting rapid interchange of components and electronically drawing electrical circuit diagrams.

Method of effecting one of several predetermined mutual different circuit connections comprising the steps of initiating a course of sequentially occurring time windows, or time frames, or time intervals, or time slots in a predetermined sequence, starting from an initial first time slot, including actuating a switch to start said sequence and maintaining actuation of said switch for at least a certain time corresponding to the first time slot in said initiated sequence, a first preset circuit connection being associated with said first time slot and being prepared upon actuation of the switch; temporally associating respective further circuit connections with respective time slots including preparing respective circuit connections associated with the respective time slots as sequential time slots occur, circuit connections associated with preceding time slots being disconnected and new circuit connections established whereby, when actuation of a switch persists for a longer period than the interval of said time slot, the circuit connections will shift at a predetermined point of time corresponding to the transition between said first time slot and the sequentially occurred time slot, and subsequently, to the transition between subsequent time slots; controlling the length of the time course by selecting a predetermined number of the sequential time slots to effect the circuit connection associated with the respective selected one of the time slots; and indicating each point of time corresponding to a time slot to provide an operator with a preceptible output of the then existing time slot of the course during each instant of time.
