Abstract: A privacy indicator is disclosed that uses a controller on an inside of a door with an indicator on the outside of the door, thereby optionally indicating a “busy” or “in use” state, or privacy request inside the door. A vertical-orientation-adjustable magnetic or acceleration sensitive switch may be used to cancel the “in use” state. An initial adjustment circuit is used to adjust the vertical position of the switch to allow for vertically misaligned mounting surfaces. The latched “in use” condition serves as a privacy request, reducing embarrassment when used in toilet stalls or bathrooms, or when other potentially embarrassing activities are being performed. Upon opening of the door, a radial acceleration is induced on a pendulum switch, whereupon the latched condition is cancelled, and the indicator no longer indicates the latched privacy request condition.
