1. An electronic switching device to be used with an exhaustible dc power source and an energy consuming load, said device comprising:

  • (a) a power switch configured to be connected between said power source and said load;

    (b) a microchip connected in parallel to said power switch and configured to control said power switch, wherein said microchip has at least one input configured to be connected to a signal switch, and wherein said at least one input transmits a signal to said microchip when the signal switch connected to said input has been activated or deactivated, said at least one input and signal switch connected thereto comprising an activation/deactivation interface to the microchip, and said at least one input and signal switch connected thereto do not form a serial element in a circuit between the power source and the load;

    (c) whereby said power switch controls energy flow from said power source to said load in response to activation and deactivation signals received through said input from the signal switch; and

    (d) an energy storage device configured to be connected to the microchip, whereby said microchip is powered by energy from said energy storage device when the power switch is conducting energy from the power source to the load, and wherein said microchip is powered by the power source when said power switch is not conducting energy from said power source to said load.
