Tray table indicator

A tray table indicator, the tray table indicator comprising

• a body having a body depth between a first surface and a second surface, the first surface of the body positioned within a vertical plane;
• a channel extending from the second surface into the body a portion of the body depth, the channel having a first extension, a curve, and a second extension, the channel having a channel depth that is consistent in the first extension, the curve, and the second extension;
• a cover secured against the second surface of the body to enclose the channel;
• and
• a magnetic ball contained within the channel between the body and the cover, the magnetic ball being movable from the first extension around the curve to the second extension of the channel in response to rotation around an axis intersecting the vertical plane by a minimum distance in a first direction, and
• 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 around the axis intersecting the vertical plane in a second direction after having rotated the minimum distance in the first direction,
• wherein the vertical plane is aligned with a side of a rotating tray table component to which the tray table indicator is secured and the axis intersecting the vertical plane is the axis around which the rotating tray table component rotates during use.
