| description | The invention provides an electronic device with a circuit for preventing contact sparks, comprising a delay circuit module, a circuit switch module and a reflex circuit module, wherein the delay circuit module is connected with a power supply and comprises a Zener diode; the circuit switch module is electrically connected with the delay circuit module and comprises a first transistor and a second transistor; and the reflex circuit module is connected with the circuit switch module and comprises an optical coupler. When the electronic device is connected with the power supply, the Zener diodeis conducted and charges the power to the first transistor to conduct the first transistor, thereby controlling opening of the second transistor and supplying current to the electronic device; and when the electronic device is removed from the power supply, the Zener diode is closed and does not charge the power to the first transistor any more, the first transistor is closed so as to control thesecond transistor to close |
