A multi purpose switching circuit is provided. The multi purpose switching circuit is connected with a main unit (60) of an electronic apparatus and includes a multi purpose switch (10). The multi purpose switch is capable of receiving multiple manual operational inputs and accordingly producing multiple command signals. The multiple manual operational inputs are identified by a pushing time and a pushing count in a predetermined time of the multi purpose switch. The multiple command signals initiate the main unit to implement multiple functions such as starting up, shutting down and resetting itself. An electronic device including such a multi purpose switching circuit is also provided.
