ABSTRACT:
An electronic switching device is described for use with microprocessors and other memory containing devices. The electronic switching device can be adjusted to provide control signals out to the microprocessor or other memory containing devices when the supply voltage common to all units goes above or falls below predetermined values. The control signals substitute an auxiliary voltage for the supply voltage when wide fluctuations occur. Further, the control signals introduce delays which allow the microprocessor or the memory containing devices to complete an internal processing step before switching in the auxiliary voltage.
