Abstract
A power saving circuit includes a variable resistor, a switch and a processing module. A power supply unit is connected between the switch and the variable resistor. The processing module is connected between the switch and the variable resistor. The switch connects with the variable resistor. The switch is capable of conducting the power supply unit and the processing module when the variable resistor is be pressed. The processing module is capable of transmitting a working signal to the switch for making the switch continuing conducting the power supply unit and the processing module when the variable resistor is unpressurized after the power is transmitted to the processing module. The processing module is capable of detecting the condition of the voltage of the variable resistor to change the working signal. The switch is capable of breaking the power supply of the processing module if the working signal is off state.
