Abstract
A power control circuit is connected between a power source and an electronic controller in a device such as a printer and includes a latchable power delivery state for delivering power to an electronic controller of the device. Temporary closure of a switch latches the power control circuit in its power delivery state. The electronic controller subsequently detects temporary closure of the switch and responds with an output signal that unlatches the power control circuit into a power non-delivery state. The power control circuit may include an associated kick-start circuit portion for causing the power control circuit to latch into its power delivery state in response to initial application of power by the power source.
