An effective tool that attaches to select whistles to that accurately manages 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, Classic CMG and Pearl Whistles. Does not fit in ACME or Fox 40, 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.

Who needs the table for answers? Not me! I can indicate whose position it is before my partners are able to ask the table. This item truly helps when working recreational games, considering parents tend to work the tables and may forget to switch the arrow.

Much better and more discreet than keeping something in your pocket. You don't even have to pull the tape off to keep it secure in the whistle. I give these away to new officials to help. I am known by one of my college colleagues as the possession official; I will have it called out and pointing direction before my partners can look to the table.
