An electrical control system comprising a controllably conductive device, an input receiving circuit and a timer circuit. The controllably conductive device selectively applies power to an electrically operated servo. The input receiving circuit receives an input signal from an input switch for selection of the motion of the control surface operated by the electrically operated servo. The input signal receiving circuit is coupled to the controllably conductive device to cause it to be conductive in response to the input signal. The timer circuit is responsive to a signal from the input receiving circuit for causing the controllably conductive device to be non-conductive if the input signal is present for greater than a selectable time period.
