Abstract: A device for powering interactive appliances in moving playground equipment includes an electrical generator mounted onto the moving element of the playground equipment, characterized by the design of the electrical generator, which includes a case (1) inside of which there is fixed a tube (7) made out of insulating material, on the tubes periphery surface there are fixed n number of coils (4). n is greater or equal to one. The coils (4) are divided from each other by separating insolating elements (3). Inside the tube it is placed a permanent cylindrical magnet (5) allowing for its sidestep movement along the tube. At the two ends of the tube (7) there are fixed rebound elements (6) The terminals of single coils or a group of connected coils (4) are terminals of the powering device, connected to the interactive appliances.
