Switch circuit

摘要

A switch circuit for switching between a first storage and a second storage. The switch circuit includes a switch, first and second control circuits, a switch control chip, and a processing chip. When the second control circuit transmits power from a power supply to the first storage, the first control circuit connects the power supply to the first storage, and connects the second control circuit to the processing chip the first storage regardless of the state of the switch. When the second control circuit transmits power from the power supply to the second storage, the first control circuit connects the power supply to the second storage, and connects the processing chip to the second storage regardless of the state of the switch.
