Abstract

An elevator hall call button includes a switch (20, 56) as well as displays (21, 54, 55) comprising matrices of light emitting diodes to provide an indication to a passenger of the imminence of arrival of the responding car. The display can be floor position (FIG. 5), flashing at a varying speed (FIG. 6) flashing at a lobby floor whenever a car approaches the lobby (FIG. 7) or in response to a lobby call (FIG. 8), an arbitrary number which reduces in response to the car approaching (FIGS. 9 and 10), or time remaining (FIG. 11).
