In said structure, two JK flip-flop, the second resistance, the 3rd resistance, the 4th resistance, electric capacity and switch composition T trigger, electric capacity, the 3rd resistance composition reset circuit, make this switch have the advantages that operating voltage range is wide, low in energy consumption, antijamming capability is strong and controllability is good.
The beneficial effects of the utility model are:
The utility model is a kind of low-power consumption Household appliance switch, two JK flip-flop, the second resistance, the 3rd resistance, the 4th resistance, electric capacity and switch composition T trigger in this switch, electric capacity, the 3rd resistance composition reset circuit, make this switch have the advantages that operating voltage range is wide, low in energy consumption, antijamming capability is strong and controllability is good.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of a kind of low-power consumption Household appliance switch of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of low-power consumption Household appliance switch of the utility model, comprise power supply, first fuse FU1, second fuse FU2, triode VT, relay K, the normally opened contact K switch-1 of relay, first resistance R1 is to the 4th resistance R4, diode D, electric capacity C, two JK flip-flop IC and switch S, the positive pole of power supply respectively with the emitter of triode VT, the first end of the first resistance R1, the first end of electric capacity C, the first end of switch S, the K trigger end of two JK flip-flop IC is connected with the J trigger end of two JK flip-flop IC, the collector of triode VT is connected with the first end of relay K and the negative pole of diode D respectively, the first end of the normally opened contact K switch-1 of relay is connected with the first end of the first fuse FU1, second end of the first fuse FU1 is first output port of Household appliance switch S, second end of the normally opened contact K switch-1 of relay is connected with the first end of the second fuse FU2, second end of the second fuse FU2 is second output port of Household appliance switch S, second end of relay K respectively with the positive pole of diode D, the first end of the 3rd resistance R3, the asynchronous set end of two JK flip-flop IC is connected rear ground connection with the first end of the 4th resistance R4, the base stage of triode VT is connected with second end of the first resistance R1 and the first end of the second resistance R2 respectively, second end of the second resistance R2 is connected with the true form output terminal of two JK flip-flop IC, the reset terminal of two JK flip-flop IC is connected with second end of electric capacity C and second end of the 3rd resistance R3 respectively, the input end of clock of two JK flip-flop IC is connected with the second end of switch S and second end of the 4th resistance R4 respectively.
