An arrangement for the call apparatus and display apparatus of an elevator has a body part which includes at least call buttons and other actuators, such as apertures for the display elements. The body part is essentially universal such that the number, size, shape and placement location of the apertures of the body part are arranged to be suited for the use of as many display variations and/or call button variations as possible, and in that an essentially thin light-attenuating film-like layer is disposed in front of the body part, which layer is fitted to allow light produced by the display elements through, but covers the apertures and other features in the body part.
