Utility model content
The purpose of this utility model is that to solve the above problems and provides a kind of automatic lamp control switch.
The utility model is achieved through the following technical solutions above-mentioned purpose：
The utility model includes the first button switch to the 3rd button switch, the first electric capacity, the second electric capacity, the one or three pole
Pipe, the second triode, relay, transformer, bulb, diode and resistance, the first end of the first button switch is simultaneously with second
The first end and the first of AC power that the first end of button switch, the first end of the 3rd button switch, relay normally open switch
End connection, the second end of the first button switch simultaneously the first end with the second button switch, the 3rd button switch the second end, after
Second end of electrical equipment normal open switch, the first end of bulb connect with the first end of primary, the second end of bulb simultaneously with
Second end of primary connects with the second end of AC power, the both ends of transformer secondary output and the two of rectifier inputs
Connection, the cathode output end of rectifier simultaneously with the first end of relay, the negative pole of diode and relay normally closed switch the
One end connect, rectifier cathode output end simultaneously with the emitter stage of the second triode, the first end of the first electric capacity and the second electric capacity
First end connection, the second end of relay simultaneously with the colelctor electrode of the second triode, the colelctor electrode of the first triode and two poles
The positive pole connection of pipe, the emitter stage of the first triode is connected with the base stage of the second triode, the base stage of the first triode and meanwhile with
Second end of the first electric capacity connects with the first end of resistance, the second end of resistance simultaneously with the second end of the second electric capacity and relay
The second end connection of normally closed switch.
The beneficial effects of the utility model are：
The utility model is a kind of automatic lamp control switch, and compared with prior art, the utility model sets multiple buttons to open
Close, the quantity of button switch does not limit, additionally it is possible to which more button switches in parallel, being installed to needs multiple positions to be mounted, makes
With convenient, and using pressing switching point bright light bubble, bulb is not in asking of declining of sensitivity by delay automatic distinguishing
Topic, there is the value of popularization and application.
Brief description of the drawings
Fig. 1 is circuit structure schematic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1：The utility model include the first button switch SB1 to the 3rd button switch SB3, the first electric capacity C1,

First button switch SB1 first end simultaneously the first end with the second button switch SB2, the 3rd button switch SB3 first end,
Relay normally open switch K1 first end connects with AC power AC first end, and the first button switch SB1 the second end is simultaneously
Second end of first end, the 3rd button switch SB3 with the second button switch SB2, relay normally open switch K1 the second end, lamp
First end and transformer the T primary first end for steeping H connects, bulb H the second end simultaneously with the second end of transformer T primary and
AC power AC the second end connection, the both ends of T level of transformer are connected with rectifier DR two inputs, rectifier DR's
Cathode output end is connected with the first end of relay K first end, diode D negative pole and relay normally closed switch K2 simultaneously,
Rectifier DR cathode output ends simultaneously with the second triode VT2 emitter stage, the first electric capacity C1 first end and the second electric capacity C2
First end connection, relay K the second end colelctor electrode with the second triode VT2, the first triode VT1 colelctor electrode simultaneously
Connected with diode D positive pole, the first triode VT1 emitter stage is connected with the second triode VT2 base stage, the first triode
VT1 base stage be connected with the first electric capacity C1 the second end and resistance R first end simultaneously, resistance R the second end while with second
Electric capacity C2 the second end connects with relay normally closed switch K2 the second end.
Operation principle of the present utility model is as follows：
Any one of the first button switch SB1 to the 3rd button switch SB3 is pressed, bulb H is lighted, transformer T decompressions,
Low-voltage circuit is powered after rectifier DR rectifications, and the first electric capacity C1 and the second electric capacity C2 start to charge up, and makes the first triode VT1 and the
Two triode VT2 are turned on, and relay K obtains electric adhesive, and relay normally open switch K1 closures, bulb H is remain on, while relay
Normally closed switch K2 disconnects, and the first electric capacity C1 and the second electric capacity C2 stop charging, and are discharged through resistance R and triode, are discharged to not
