A remote control unit is electrically connected to a toy only by a two conductor cord. An electronic control unit located within the toy includes a signal generator and a controller for receiving the output signals and controlling at least two actions of the toy by detecting predetermined period variations in the received output signals, a first action enabled by a first predetermined period variation and a second action enabled by a second predetermined period variation. The remote control unit is electrically connected to the signal generator only by the cord and includes a switch array having at least a first switch in parallel with a second switch so that when the first switch is closed to cause the first predetermined period variation and when the second switch is closed to cause the second predetermined period variation.
