Abstract

A tray table indicator includes a channel, a cover, and a magnetic ball. The channel has a first extension, a curve, and a second extension, and the cover encloses the channel. A magnetic ball is contained within the channel and is movable from the first extension around the curve to the second extension of the channel in response to rotation of the rotating tray table component by a minimum distance in a first direction. The curve of the channel is configured to prevent gravity from returning the magnetic ball to the first extension from the second extension in response to rotation of the rotating tray table component in a second direction after having rotated the minimum distance in the first direction.
