Gravitrax Power Element Switch Trigger Expansion Set

Ravensburger's interactive ball track system.

This set includes the individual POWER elements from the Starter Set Switch. You can install the trigger anywhere on the track to activate the Switch. This way, the next ball will go along a different track! This set also works with all the other POWER elements for even more action on the track.

The GraviTrax® ball track system lets you playfully explore gravity, and with various expansions, it can be expanded for endless building and play fun! Add even more speed with the expansion sets.
