The electrical supply connections are shown in fig 5. Electrical supply to the motors is fed through the brushes connected to the horizontal shaft in between the spheres. The two brushes connected to the shaft make contact with the metal strips laid along the circular path and serve as supply terminals. Whenever these two brushes make contact with the metal strips, the corresponding motors get activated through the line connection made on the metal strips and therefore perform the desirable task of lifting and lowering of the platform base.
