  • Patent number: 4355483
    Abstract: A switch mechanism for use in an electronic toy having a printed circuit board, a portion of which has a pattern of printed wiring with contacts thereon. A body of conductive resilient material, disposed in the housing of the toy with the printed circuit board, has a base portion with an opening therein. Part of the base is a bridge across the opening, having a push button and a web flexurably connecting the push button to the base. The body is disposed in juxtaposition with the board portion over the contacts with the push button extending through an opening in the housing to present an end of the button which, when depressed, causes a connection to be made between the board contacts through the conductive material of the body for operating the electronic circuits of the toy. A plurality of push buttons may similarly be disposed as part of individual bridges on the base for operating different circuits of the toy when depressed.
