The 43-piece switch extension is ideal for connecting multiple tracks. After each ball passes through the switch, it flips, ensuring that subsequent balls always take a different path. This allows builders to decide which ball reaches which target. With this set, a small standalone marble run can be built, or the components can be integrated into a larger marble run.

100% compatible with building blocks from other manufacturers: All Hubelino products fit perfectly with blocks from other well-known manufacturers, thereby optimally complementing the existing stock of building blocks.

Made in Germany for excellent product quality: All Hubelino products are manufactured exclusively in Germany under the highest quality standards.

Learning through play with STEM building sets: Hubelino products prioritize a balanced relationship between fun and educational value. Therefore, a learning aspect is always the focus during the development of new products, transforming them into toys with educational benefits through clever design.

The 43-piece switch extension includes numerous track elements, building blocks, a base plate, and balls, with a total of two switches. This set allows for the construction of a small standalone marble run, but the greater fun comes from integrating the switch into a larger marble run.

With the modular and compatible marble run, where nothing wobbles or shifts, spatial imagination and basic physical principles are conveyed. Whether with or without building instructions, the colorful setup trains the ability to follow sequences, stimulates working memory, and develops analytical thinking skills.
