ABSTRACT OF THE DISCLOSURE It is possible, with this apparatus, to produce shaft-information dependent upon specific elevator-cabin positions without installing actuating elements in the elevator-shaft or emitters in the elevator-cabin. To this end, a memory is provided in which specific locating numbers, identifying shaft-locations, are stored, the said locating numbers being transferred, one after the other, as the elevator-cabin travels in the shaft and in the direction of travel, to a register Pulses, from a pulse- generator, driven by the said elevator-cabin, are added in a counter to locating numbers corresponding to the position of the cabin in the shaft. Locating numbers in the counter and in the register are compared with each other in a comparator. If they are the same, a shaft- information signal is produced and a switching element, associated with the particular shaft-position, is activated.
