Connect, the cathode of rectifier simultaneously with silicon-controlled cathode, the anode of voltage-stabiliser tube, the first end of the first capacitance, the second capacitance the
One end is connected with the first pin of Shi Ji integrated chips, silicon-controlled control terminal by second resistance with when base integrated chip the
Three pins connect, and the anode of the second end of first resistor and diode connects, the cathode of diode simultaneously with the cathode of voltage-stabiliser tube,
The second end of first capacitance, when base integrated chip the 4th connected with the 8th pin, when base integrated chip second pin pass through
3rd resistor is connect with the first metal touch piece, when base integrated chip the 6th pin pass through the 4th resistance and the second metal touch
Piece connects.
The beneficial effects of the utility model are：
The utility model is a kind of electronic touch switching device, and compared with prior art, the touch point of the utility model is set
Chip, touch chip only need base integrated chip in order to control when being calculated as unlatching and touch and close two touch sheets of touch, and using
Extremely low signal can touch-control, therefore, open and close are separately controlled, control high sensitivity, have the value of popularization and application.
Description of the drawings
Fig. 1 is the circuit structure schematic diagram of the utility model.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1：The utility model include first resistor R1 to the 4th resistance R4, the first capacitance C1, the second capacitance C2,
Rectifier DR, controllable silicon SCR, diode D, voltage-stabiliser tube DW, when basis set at chip IC, the first metal touch piece A and the second metal
The first end of touch sheet B, first resistor R1 are connect with the first end of the first end of AC power AC and load electrical appliance FZ simultaneously,
The second end of load electrical appliance FZ is connect with the first input end of rectifier DR, the second input terminal and AC power of rectifier DR
The second end of AC connects, and the anode of rectifier DR is connect with the anode of controllable silicon SCR, the cathode of rectifier DR and meanwhile with it is silicon-controlled
The cathode of SCR, the anode of voltage-stabiliser tube DW, the first end of the first capacitance C1, the first end of the second capacitance C2 and Shi Ji integrated chips
The first pin of IC connects, the control terminal of controllable silicon SCR by second resistance R2 with when basis set connect at the third pin of chip IC
Connect, the second end of first resistor R1 connect with the anode of diode D, the cathode of diode D at the same with the cathode of voltage-stabiliser tube DW, the
The second end of one capacitance C1, when basis set connected with the 8th pin at the 4th of chip IC, when basis set at chip IC second pin
Connect with the first metal touch piece A by 3rd resistor R3, when basis set at chip IC the 6th pin by the 4th resistance R4 with
Second metal touch piece B connections.
The operation principle of the utility model is as follows：
When touching the first metal touch piece A with hand, when the inductive signal of human body clutter is transferred to by 3rd resistor R3
Basis set is at the second pin of chip IC, and basis set is overturn at chip IC when making, and third pin exports high level, defeated through second resistance R2
Enter to the control terminal of controllable silicon SCR, controllable silicon SCR conducting, load electrical appliance FZ is switched on, and is powered on, when touching the with hand
When two metal touch piece B, when basis set at the 6th pin of chip IC as reset terminal, when basis set resetted at chip IC, third is drawn
Foot output becomes low level, controllable silicon SCR cut-off, and load electrical appliance FZ is disconnected, and closes power supply.
