ABSTRACT:
An elevator car position indicator utilizes a plurality of indicating pins whereby a visually impaired passenger in the elevator car is able to determine the actual car position by touch. The pins are arranged in a Braille configuration at a face plate of the car control station. The indicating pins are connected with armatures of electromagnets and are guided in apertures formed in the face plate. The electromagnets are connected through a control circuit to a coding circuit to which is supplied the car position information wherein the car position is transformed into the corresponding number in Braille and the corresponding indicating pins are pushed out from the face plate.
