Arrangement for operating planetaria

The invention relates to an arrangement for operating planetaria with the aim of increasing operating convenience and useful value. The object is to use a small number of operating elements to give a maximum number of possibilities of presentation as well as to make the overall layout of the operating elements easier to appreciate and to simplify the design of the operating console. The arrangement comprises an operating console, on which operating elements for initiating switching and control functions are provided. These operating elements are assigned to switching and/or control functions of differing order and can be interconnected by means of logic circuits known per se in order to input signals into a computer or into a unit for realising the functions.
