An effective tool to accurately manage alternating possession throughout all levels of amateur basketball.


  • Each time there is an alternating possession situation, flip the black and white switch!.
  • When the switch is in the up (white) position, it represents the home team. When in the down (black) position, it represents the visiting team or team with the darker jerseys - can be determined by sight or feel.
  • Possession switch's double sided tape allows it to easily be secured in Fox 40 classic and classic whistles with cushioned mouth grip (manufacturer of switch not affiliated with Fox 40 - See below for more info).
  • Fits Fox 40 Classic Whistles. Does not fit in ACME or Fox 40 Pearl, Fuziun, Dolfin, Sonik, Classic Eclipse, Epik or Mini Whistles.


  1. Set your switch in the up position (white showing).
  2. Make sure the surface of your whistle is clean. Peel off the protective cover on the tape to expose the adhesive.
  3. Insert your switch into the whistle.
  4. When your switch is in place, press firmly on switch to create a good seal between switch and whistle.
  5. To insure the best installation results and a maximum seal between the whistle and your switch installation temperature should be from 70°F to 100°F.

Love this. So helpful keeping possession on the court when the table can't be trusted :)

The Alternate possession switch is a great tool for game management. The people at the score table are usually good, but this allows you to keep track incase they error and to not have to count on the score table.

Easy way to keep up with the possession arrow. Just look down. Don't ever look at arrow!
