Description
Technical field
This utility model relates to a kind of electrical switch, a kind of simple and practical electronic switch control circuit.
Background technology
Switch is the switch element that field of power electronics is conventional, main electricity consumption is cut off and opens electric loop, from the plug-in strip of earliest period intelligent electronic switch till now, people are the most constantly developed for intellectuality, the hommization research of switch, and it is along with the extensive application in people live of the various household electrical appliance, more and more higher to the diversity requirement of high-performance electronic switch.Wherein power failure self-lock switch can effectively prevent because having a power failure the waste of energy sent a telegram here again and cause, therefore suffer from liking of people, but self-lock switch many uses Control in the market, relay controls owing to using mechanical contact, therefore it is easily damaged, service life is short, and anti-interference is poor, therefore needs to be improved.
Utility model content
The purpose of this utility model is to provide a kind of simple and practical electronic switch control circuit, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of simple and practical electronic switch control circuit, including resistance R1, audion V1, diode D1 and button K2, the emitter stage of one end connecting triode V1 of described resistance R1 and power supply VCC, the other end of resistance R1 connects button K1 and button K2, the other end of button K2 connects resistance R3, electric capacity C1, the anode of diode D1 and the colelctor electrode of audion V2, the base stage of the other end connecting triode V2 of button K1, the emitter stage of audion V2 connects the other end of electric capacity C1, load A and the emitter stage of audion V3, the base stage of audion V1 connects resistance R2, the colelctor electrode of the other end connecting triode V3 of resistance R2, the colelctor electrode of audion V1 connects the other end and the other end of load A of resistance R3.
As preferred version of the present utility model: described button K1 and button K2 is touch key switch.
Compared with prior art, the beneficial effects of the utility model are: the simple and practical electronic switch control circuit simple in construction of this utility model, components and parts are few, utilize key switch and audion composition self-locking control module, compared to traditional relay, there is longer service life and lower cost, therefore there is low cost, life-span length and advantage easy to use.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of simple and practical electronic switch control circuit.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, a kind of simple and practical electronic switch control circuit, including resistance R1, audion V1, diode D1 and button K2, the emitter stage of one end connecting triode V1 of described resistance R1 and power supply VCC, the other end of resistance R1 connects button K1 and button K2, the other end of button K2 connects resistance R3, electric capacity C1, the anode of diode D1 and the colelctor electrode of audion V2, the base stage of the other end connecting triode V2 of button K1, the emitter stage of audion V2 connects the other end of electric capacity C1, load A and the emitter stage of audion V3, the base stage of audion V1 connects resistance R2, the colelctor electrode of the other end connecting triode V3 of resistance R2, the colelctor electrode of audion V1 connects the other end and the other end of load A of resistance R3.
Button K1 and button K2 is touch key switch.
Operation principle of the present utility model is: during use, push button K1, now the base stage of audion V3 obtains electric and turns on, the collector current of audion V3 is the base current of audion V1, therefore audion V1 conducting, audion V1 enters degree of depth saturation, now output voltage, close to supply voltage VCC, load A obtains electric, voltage is added in the base stage of audion V3 after resistance R3 and diode D1 simultaneously, keep audion V3 constant conduction, even if therefore unclamping button K1, circuit also can normally work, when needs close closed circuit, only need to push button K2, now the base stage of audion V2 obtains electric, it is shorted out being added in the electric current of audion V3 base stage, therefore audion V3 cut-off, and then audion V1 cut-off, the electric loop of load A disconnects.
