The Battery Interrupter is a battery interface control for toys designed to create switch compatibility for non-adapted toys for individuals with fine motor or physical disabilities. It is a cable that fits between any battery-operated toy or device and a switch, permitting the toy or device to be operated by the switch. It interrupts the power by inserting a disc between on of the batteries and the adjacent anode. There are two models available for battery sizes AA and AAA or C and D batteries. The Battery Interrupter works with devices that have an on/off switch, but it will not work with toys that are squeezed to activate them.
