ABSTRACT:
An electronic circuit for use with an exhaustible power source and at least one load such as a light bulb, a radio or motor, includes a microchip with an input that transmits a signal to the microchip when the load is activated or deactivated. The input does not form a serial link between the power source and the load. The power switch, by on/off switching, controls energy flow from the power source to the load. The input to the microchip acts as an activation/deactivation user interface. The microchip allows the user to select a specific load, specific functions for the selected load based on the time duration of activation signals, the time duration between activation signals and the number of activation signals at the input.
