The Bright/Switch is a unique design that makes for a great night lite for a child. The Bright/Switch looks like a large button switch that has a pivot point on the bottom of the button. On the face, you will see printed "On" and "Off". To use your Bright switch, first make sure that it is on a flat surface. Then just push the Bright/Switch to the on position with the on position touching a flat level surface. Then to turn it off, just push the Bright/Switch to the off position with the off position touching a flat level surface. The Bright/Switch uses three "AA" batteries (not included). The Bright/Switch measures just 6.5 inches x 3 inches x 2 inches.
