摘要： A first device includes an outrush circuit including a resistor electrically disposed in series with first and second terminals of the first device and a switch electrically disposed in parallel with the resistor. The switch is controlled by an external signal received by the first device from a second device when the first device is communicably connected to the second device and the second device is electrically connected to the first and second terminals. When the first device receives the external signal, the switch is switched on after a startup time from receiving the external signal, such that electric current from a power source substantially passes through the switch. When the first device does not receive the external signal, the switch is switched off, such that electric current from the power source substantially passes through the resistor. The resistor limits electric current to the second device.
