Abstract: A display and control element is described which comprises several lighted push buttons which are--if necessary--mutually resetable and are mounted on a board insertable into a casing. The operating of the individual lighted push buttons as well as the optional mutual resetability is electrically determined by means of circuits. The arrangement and setting of such circuits is adjustable without change of the wiring by means of code switches, crossbar distributors, plug-in connectors, etc. or by means of the program (software) of a microprocessor which preferably is mounted on a separate plug-in board. For more complicated plants to be controlled several such elements may be combined in a casing and, if necessary, also several such casings may be connected to each other by means of data lines.
