Elevator car call buttons indicating car floor position

摘要

Registered car calls are indicated in the car call buttons of an elevator car operating panel by illuminating one of the car call buttons with a first illumination characteristic, and the floor position of the elevator car within the building is indicated by illuminating any of the same car call buttons with a second illumination characteristic, different from the first illumination characteristic. One part of the car call button (such as the center) may be used to indicate registered car calls and another part of the car call button (such as the ring) may be used to indicate car position (or vice versa). Registered car calls may be indicated by steady or invariant illumination from the car call button while car position is indicated by illuminating the appropriate car call button with flashing illumination. Colors may also be used.
