The GraviTrax Power elements Switch and Trigger include both electronic components as part of the Ravensburger marble run system. With the new GraviTrax Power elements Switch and Trigger, new possibilities can be explored. The elements communicate with each other via radio, which is visualized through three color channels. When a signal is sent from the Trigger to the Switch, the Switch automatically adjusts. The player has more control over the course of the track. They can vary the paths of the marble through the track, significantly extending the running time of the course. Even more action, power, and fun with GraviTrax.

GraviTrax is a flexibly expandable, interactive marble run system for children aged 8 and up: With GraviTrax, children, teenagers, and adults can build not only simple marble runs but also create unique marble run worlds. By freely designing the marble runs and exploring the rolling behavior of the marbles, understanding of science is sharpened, and gravity is experienced up close. The STEM label on Ravensburger products indicates a category of games that makes science playfully accessible. STEM (Science, Technology, Engineering, Mathematics) corresponds to the German MINT (Mathematics, Computer Science, Natural Sciences, Technology). Through various expansions, children can enlarge their marble runs and redesign them repeatedly.
