  • Patent number: 5454448
    Abstract: Elevator car call buttons and hall call buttons are illuminated in a first fashion (such as a first color or intermittent flashing) to indicate that the service corresponding to that call button is available to passengers (while buttons corresponding to unavailable service would have either no illumination or different illumination); the buttons then become illuminated in a distinctly different way when a service call corresponding to that button has been registered. The illumination may be thin rings surrounding the call button switch or the call button switch itself; many variations of color, position, and flashing vs. steady are disclosed.
