PROBLEM TO BE SOLVED: To provide a switch circuit that performs ON/OFF by means of a hardware circuit and an electronic device including the same.SOLUTION: A switch circuit includes a control unit connected to the power supply, and a key switch unit connected between the power supply and the control unit. When the key switch unit is turned on in response to an operation by a user to turn on the connection between the power supply and the control unit, the control unit receives a supply voltage from the power supply and accumulates energy to generate a first control signal. The first control signal turns on the power supply to power a load. When the key switch unit is turned on in response to an operation by a user to turn off the connection between the power supply and the control unit, the control unit discharges energy to generate a second control signal. The second control signal turns off the power supply to stop powering a load. |
