The FIBA-compliant Basketball Possession Alternation Arrow is an arrow-shaped light indicator that is positioned and operated from the officials' table – Basketball. This arrow is made up of high-brightness red LEDs and a wide viewing angle, so that it can be seen clearly from any point on the court.
The dimensions of the luminous arrow are 20x20 cm and the size of the arrow as a whole, including the housing, is 30x28 cm, as shown in the drawing. The direction of the arrow is selected using two push buttons on the rear. Both arrows overlap and are positioned in the centre of the display frame.
An additional third button is also located on the back that turns off the Possession Alternation Arrow Indicator. This indicator device operates on 220V mains voltage.
