The unit 205 includes a selection switch & and a first resistor Ri, which is connected to the control unit 207, and the other end is selectively connectable to the ground or connected to the power conversion unit by the first resistor Ri. The delay single S 203 includes a second resistor & a third resistor & and a third (four) Ql ' wherein the base and the collector of the third transistor Q1 are electrically connected to the power source via the resistor R2 and the third resistor R3, respectively The conversion unit 201 has an emitter electrically connected to the control unit. The control unit 207 includes a controller 301, a fourth resistor R4, a fifth power, and a second transistor ~. The controller 3〇1 includes a trigger signal input, a reset terminal 3, an enable terminal 3〇lc, a ground terminal, and a terminal 301f. The trigger signal input terminal 3〇ia is electrically connected to the selection switch I′ to be torn by the selection switch 在ι in the grounding or power conversion unit:: the selection generates the trigger signal ′, and the output terminal 3〇if outputs the driving signal reset terminal. 3〇lb is active low, which is connected to the power conversion unit, 200935740 == The DC voltage output by the power conversion unit 201 causes the control. The round end 301f of the 〇1 is valid. The enable terminal 3〇lc is connected to the first three, and the emitter of the body Q1 is used to receive the DC current from the delay unit: the ground is $3〇le grounded.

The emitter of the second triode is grounded, and the electrode is electrically connected to the switch unit 2〇9. The fourth resistor is connected to the base of the second transistor Q2 and the common terminal of the fifth resistor & the other end is grounded, fourth. Resistor R4 provides a bias voltage for the second triode 〇2. The switch unit 70 209 includes an anti-interference module 2〇9a and a relay module drain. The anti-jamming module 209a includes a sixth electric & R6 and an optocoupler 302. The photocoupler 3〇2 includes a light-emitting diode 3〇. And a photodiode 302b. The positive electrode of the light-emitting diode is electrically connected to the power conversion unit 2〇1 by the sixth resistor & the receiving power supply unit 2〇1 is provided for the operation of the light-emitting diode 302a; the light-emitting diode 3. The negative electrode is electrically connected to the collector of the second triode of the control unit 2G7. The collector of the photodiode 302b is electrically connected to the power conversion unit 2, and the emitter is electrically connected to the relay module 209b. The power conversion unit 2〇1 is connected between the collector and the emitter of the phototransistor 302b. Turning on the converted power supply to the relay module 209b, so that the relay module 2 is powered on. The relay module 209b includes a capacitor C, a seventh resistor core, a relay 3〇3, and a circuit switch K:2. The circuit switch K; 2 is connected between the external power source 1 and the electronic device 400 for receiving an input of the external power source 1 . The capacitor c and the seventh resistor R7 are electrically connected in series between the emitter of the phototransistor 3〇2b=ground for shunting when the photocoupler 3〇2 is turned on. The relay also 11 200935740 is electrically connected between the photosensitive triode 3〇2b and the ground for controlling the circuit switch • K2 is closed to connect the external power supply ίο to the electronic device 400, or to control, the circuit switch is disconnected to stop The external power supply 1〇 supplies power to the electronic device 4〇〇. When the control switch 100 is closed, the power conversion unit 2〇1 receives the input of the external power source 10, and outputs the DC voltage after the wheel is converted, and the base of the first triode Qi receives the DC voltage by the second resistor. Turning on, and its collector transmits the DC voltage received by the third resistor h through its emitter to the enable terminal 301c of the controller 301, causing the controller 301 to be powered up. The reset terminal 301b is active low, and it receives the DC voltage of the power conversion unit to tear the output and is invalid. At this time, the user operates the selection switch 1 to generate a trigger signal. The trigger signal input terminal 301a receives the trigger signal generated by selecting 1 off Ki, so that the output end of the controller continuously outputs the driving signal as K, and the second triode 〇 connected to the output end 301f of the controller 301 via the fourth resistor R4. The collector and the emitter of the second electrode are turned on, so that the light-emitting diode 302a of the photocoupler 302 connected between the collector of the second triode Q2 and the power conversion unit 201 is turned on, so that the photo-transistor 302b The collector and the emitter are turned on, and the output of the power conversion unit 2 is transmitted to the DC module. The relay module b receives the DC power transmitted by the photoelectric light coupler 3〇2, and the control circuit switch K2 is closed, so that the external power source 10 is externally driven by the switch device to drive the electronic device_. When the user operates the selection switch, the heartbeat trigger signal 'controller 3()1 receives the trigger signal again and generates the flipping and no longer outputs the driving signal, thereby turning off the second triode Q2, and the photoelectric light combination 12 200935740 is also cut off. The DC voltage output from the power conversion unit 2〇1 cannot be transmitted to the relay 303'. The relay 303 controls the circuit switch K2 to be disconnected. The power supply 丨〇 cannot output a voltage to the outside through the switching device 200. When the control switch 100 is turned off, the power conversion unit 2〇1 does not have an input of the external power source 10, and thus the power conversion unit 2〇1 does not have a DC voltage rotation. Delaying the first triode Qi of the single 7L 203 is cut off, the controller 3〇1 stops = 'At this time, how the user operates the selection switch & no trigger signal can be generated, the second triode Q2 is cut off, photoelectric coupling The device 3〇2 is also turned off, the relay 3〇3 has no power supply, the circuit switch Kz is turned off, and the external power source 1〇 cannot output voltage to the outside through the switching device 200. When the control switch 100 is closed again, the power conversion unit 2〇1 receives the input of the power source 10, and converts the input and outputs a DC voltage. The second-pole QA of the delay unit 203 receives the DC voltage and is turned on. And transmitting the DC voltage to the controller 3〇1 through its emitter, causing the controller to operate up. At this time, if the user does not operate the selection switch & select, 开关, switch 1 does not generate a trigger signal, the controller does not output the drive signal, the second-pole Q2 is turned off, the photoelectric aligner is also turned off, the power conversion single The DC voltage output from 疋201 cannot be transmitted to the relay. For example, if the relay control circuit switch K2 is turned off, the external power supply 〇 cannot output voltage to the outside through the switch. If the user operates the selection switch ^ to generate a trigger signal, thereby causing the controller 3〇1 to generate a driving signal, the second triode/conducting combiner 302 is turned on, and the relay 303 receives the power conversion: 2〇1 conversion rounds out The DC voltage is controlled by the control circuit switch κ, and the external power source 10 outputs a voltage to the outside through the switching device. 13 200935740 The above switching device 200 generates a trigger signal by changing the input of the input unit 205, so that the control unit 207 outputs a driving signal, and drives the switching unit -209 to output a voltage. The switching device 200 stops working when the control switch 100 is turned off. When the control switch 1 is closed, if the input of the input unit 2〇5 is not changed, the switching unit 2〇9 of the switching device 200 does not close, but the input is changed. Upon the input of unit 205, the switching unit 2〇9 of the switching device 2 is closed, closing the circuit between the electronic device 400 and the external power source 1〇. Therefore, the problem of automatically turning on the electronic device 4 after the control switch 1 is closed and forgetting to turn off the electronic device after the control switch 1 is turned off is effectively solved, thereby avoiding waste of electricity and increasing people. The burden can also prevent the electronic device 400 from automatically starting, which affects people's rest.
