Sliding signs work manually. These SmartSliders consist of two panels - a static panel with two different messages on either side and a moveable top panel. You can easily show one message out of the two to show the current room status. To change the message on the sign, just slide the top panel horizontally and show either the message at the right or the left. For example - Before using the bathroom, the user can display “Occupied” on the Occupied and Vacant Sign by covering the other side with the top slider. After coming out, the person can manually slide the top panel covering “Occupied” and displaying “Vacant” for other users.
