Description
Technical field
This utility model relates to a kind of switch, specifically a kind of double; two touch power switch control circuit.
Background technology
Switch is modal electrical equipment in daily life, its on-off mode of traditional switch mostly is key switch or knife switch, major part electrical outlets all uses the mode of this kind of mechanical switch or directly plug to control at present, mechanical switch, because touching has error, has abrasion, has life-span number of times, is therefore easily damaged after long-time use.And mechanical switch can produce very big immediate current when connecting, the contact of switch shrapnel easily produces sparking, sparking is also easy for making contact oxidation cause switch contact bad, may result in switching function to lose efficacy, and directly the socket of plug-in uses and will manually plug every time, in-convenience in use, therefore need to be improved.
Utility model content
The purpose of this utility model is in that to provide a kind of double; two touch power switch control circuit, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
nullA kind of double; two touch power switch control circuit，Including neon lamp H1、Bidirectional thyristor Q1、Bidirectional thyristor Q2 and electrode slice A，One end of described electrode slice A connects resistance R1，The other end of resistance R1 connects neon lamp H1，The other end of neon lamp H1 connects a main electrode of bidirectional thyristor Q1、One main electrode of bidirectional thyristor Q2 and 220V alternating current，The other end of 220V alternating current connects resistance R2、Resistance R3、The colelctor electrode of audion V1 and load L，The other end of load L connects another main electrode of neon lamp H2 and bidirectional thyristor Q1，The other end of resistance R2 connects the other end of neon lamp H2，The other end of resistance R3 connects another main electrode of bidirectional thyristor Q2 and the control pole of bidirectional thyristor Q1，The emitter stage controlling pole connecting triode V1 of bidirectional thyristor Q2，The base stage of audion V1 connects resistance R4，The other end of resistance R4 connects electrode slice B.
As preferred version of the present utility model: described electrode slice A and electrode slice B all uses copper sheet to make.
Compared with prior art, the beneficial effects of the utility model are: this utility model double; two touch power switch control circuit simple in construction, components and parts are few, the two ore control to load is realized in conjunction with bidirectional thyristor by two Touching electrodes, there is compared to traditional mechanical switch longer service life and reaction sensitivity, therefore there is the advantage that type is stable, cost is low and easy to use.
Accompanying drawing explanation
Fig. 1 is double; two circuit diagrams touching power 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 obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1，In this utility model embodiment，A kind of double; two touch power switch control circuit，Including neon lamp H1、Bidirectional thyristor Q1、Bidirectional thyristor Q2 and electrode slice A，One end of described electrode slice A connects resistance R1，The other end of resistance R1 connects neon lamp H1，The other end of neon lamp H1 connects a main electrode of bidirectional thyristor Q1、One main electrode of bidirectional thyristor Q2 and 220V alternating current，The other end of 220V alternating current connects resistance R2、Resistance R3、The colelctor electrode of audion V1 and load L，The other end of load L connects another main electrode of neon lamp H2 and bidirectional thyristor Q1，The other end of resistance R2 connects the other end of neon lamp H2，The other end of resistance R3 connects another main electrode of bidirectional thyristor Q2 and the control pole of bidirectional thyristor Q1，The emitter stage controlling pole connecting triode V1 of bidirectional thyristor Q2，The base stage of audion V1 connects resistance R4，The other end of resistance R4 connects electrode slice B.
Electrode slice A and electrode slice B all uses copper sheet to make.
Operation principle of the present utility model is: neon tube H1, H2 and photoconductive resistance R3 in circuit constitute photoelectrical coupler.When touching sheet metal A with finger, H1 is luminous, makes R3 resistance diminish, and then bidirectional thyristor Q1 turns on because obtaining enough trigger currents, therefore load L obtains electric work, meanwhile, 220V alternating voltage makes H2 luminous, and this light also impinges upon on R3, so at this moment, stopping even if touching, bidirectional thyristor Q1 stills remain in the state of conducting, and namely L remains in that duty.Resistance R4, electrode slice B and audion V1 in figure form, after H lights, if touching sheet metal B, then the base stage of audion V1 must conduct, bidirectional thyristor Q2 turns on because obtaining enough trigger currents, makes Q1 end because it controls short circuit between pole and main electrode, and load A dead electricity quits work.And then realize the function of double; two touch control.
