A switch circuit including a control unit and a voltage level adjusting circuit is provided. The control unit has a first end, a second end, and a third end. The first end of the control unit receives a first voltage, and the voltage difference between the first end and the third end is steady. In addition, the voltage level adjusting circuit has a switch which is determined whether or not turning on according to the voltage on the second end of the control unit, so as to determine whether driving a load or not. The voltage level adjusting circuit is used for adjusting a bias of the load on driving. The switch has a source. The voltage on the source is varied following the ON/OFF of the switch, and the voltage on the third end of the control unit is varied following the voltage on the source.
