Abstract
A magnetic switch and children's apparatuses, such as print media apparatuses and plush dolls, which include magnetic switches are disclosed. One magnetic switch includes a first conductor and a second conductor spaced apart from the first conductor. A third conductor is disposed under the first and second conductors, the third conductor being formed from a magnetic material. A magnet is also included, the magnet being adapted to move the third conductor towards the first and second conductors so as to form a conductive bridge. Another magnetic switch includes a first conductor and a second conductor spaced apart from the first conductor. A first magnet is disposed under the first and second conductors. A second magnet is also included, the second magnet being adapted to move the first magnet so that the first and second conductors form a conductive bridge.
