ABSTRACT:
A lighted and sounding yo-yo is provided with a single heavy duty battery in a first hollow shell section, and a lamp in both hollow shell sections. Flexible electrical conductors connect the lamps to the battery. A centrifugal switch is joined with the conductors in the second shell section so as to actuate the lamps only during rotation of the yo-yo. An audible electrical signal device is also located in the lighting circuit of the second shell. A second modification of the centrifugal switch is also shown. The heavy weight of the battery shell as compared with the light weight of the other shell causes the battery shell to dominate the yo-yo in the manner of a gyroscopic action to obtain rotational stability.
