Description of drawings
Fig. 1 is the structural representation of on/off circuit of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further elaborated.
As shown in Figure 1, on/off circuit for fish deteclor of the present utility model, comprise: the first metal-oxide-semiconductor M1, the first diode D1, the first push-button unit K1, the first triode Q1 and eight resistance R 1-R8, wherein, the source electrode of the first metal-oxide-semiconductor M1 is as the electrical input that supplies of described on/off circuit, the drain electrode of described the first metal-oxide-semiconductor M1 is as the power supply output of described on/off circuit, described for electrical input respectively with an end of the first resistance R 1, one end of the second resistance R 2 links to each other, the other end of the first resistance R 1 links to each other with the negative pole end of the first diode D1 by the first push-button unit K1, the other end of the second resistance R 2 is connected to the grid of the first metal-oxide-semiconductor M1 and the collector electrode of the first triode Q1 links to each other, the emitter of the first triode Q1 is coupled to ground, base stage respectively with an end of the 8th resistance R 8, one end of the 5th resistance R 5, the negative pole end of the first diode links to each other, and the other end of the 8th resistance R 8 is coupled to ground; The positive terminal of the first diode Q1 links to each other with an end of the 3rd resistance R 3, and the other end of the 3rd resistance R 3 links to each other as the second control terminal IO mouth 2 and with an end of the 4th resistance R 4, and the other end of the 4th resistance R 4 is coupled to ground; The other end of the 5th resistance R 5 links to each other with an end of the 6th resistance R 6 and is coupled to ground by the 7th resistance R 7, and the other end of the 6th resistance R 6 is as the first control terminal IO mouth 1.
Here, the first metal-oxide-semiconductor M1 is the NMOS pipe, and the first triode Q1 is the NPN triode.
