Magic Bean / switch

Magic Bean
Magic Bean

Magic bean provides a brand new way to use a switch---squeezing! It is not only funny, but also very safe with waterproof and dustproof structure.

There is a metal ball inside the rubber hull. The ball connects a wire with a resistance. When the ball moves, the resistance value will change. As a result, the current will change, just like a slide rheostat. Beacuse of its entire seal structure, magic bean is free from water and dust---very easy to be cleaned and safe for children.
