You can decide if you want to keep your door open, closed or in automatic mode with the three position switch. You might want to keep the coop closed if you have young chickens that are too small to go out. Another reason is that you may need to let your chickens know that the coop is their home.
The switch is located on the top of the Ladies First Chicken Door Opener. On the inside of the box it is attached to a 6 foot cord. This cord gives you the option to move the switch to another location easily. In the pictures, the switch is attached to the included aluminum plate on a piece of wood, which represents the wall of your coop.
