A time switch device for X-ray diagnostic apparatus, in particular for the preparation of tooth or dental exposures, including a knob for the setting of the exposure periods and which has a time scale on a scale carrier associated therewith. The knob has associated therewith a symbol carrier which, in the displacement direction of the knob, is adjustable relative to the knob and to the time scale, on which there are drawn the symbols of the objects which are to be X-rayed at such a spacing relative to each other whereby, upon the setting of one symbol on the exposure period associated therewith, the other symbols are then located opposite to the exposure periods which are associated therewith.
