A switch adapted battery operated toy is a toy that has been modified so that a child with a disability can press a switch and activate the toy. The necessary modifications are easy for most adults with just a few tools and supplies from your local electronics store or some hardware stores.To make your battery operated toy work with a single switch, you need to make a copper wafer that “interrupts” the flow of electricity from the battery to the motor, lights, or sound of the toy. You then plug your switch into the phone jack connected to the copper wafer. To activate the toy, you touch the switch and close the circuit of electricity, which causes to toy to turn on.
