Abstract
An elevator car has at least one balustrade attached to a roof of the elevator car, which balustrade can be pivoted about a rotation axis between a folded-down position, in which the balustrade is arranged essentially horizontally, and a raised position, in which the balustrade is arranged essentially vertically. The balustrade is mechanically coupled to a 3-state switch, which switch can adopt three different switching states. The balustrade and the 3-state switch thus cooperate such that the 3-state switch adopts a first switching state when the balustrade is in the folded-down position, the 3-state switch adopts a second switching state when the balustrade is in the raised position, and the 3-state switch adopts a third switching state when the balustrade is in neither the folded-down position nor the raised position.
