Abstract
A single switch is utilized within a common ground line to control the current flow through a plurality of loads, whereby power to all of these loads may be interrupted by opening the system ground return so that power can be supplied to a particular component of the circuit, a microprocessor, to the exclusion of all remaining components by the operation of a single switch.
