Embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings：

As shown in Figure 1：The utility model includes infrared sensor H, first resistor R1 to the 5th resistance R5, electric capacity C, three poles Pipe VT, counter chip IC, controllable silicon SCR, the first rectifier DR1, the second rectifier DR2, transformer T, the first diode D1 With the second diode D2, infrared sensor H the first pin emitter stage with triode VT, the tenth of counter chip IC the simultaneously Six pins, the 5th resistance R5 first end connect with the first rectifier DR1 cathode output end, and the second of infrared sensor H draws Pin is connected with first resistor R1 first end, infrared sensor H the 3rd pin while first end, 3rd resistor with electric capacity C R3 first end, counter chip IC the 8th pin, the negative pole of controllable silicon SCR, the first rectifier DR1 cathode output end and Second rectifier DR2 cathode output end connection, first resistor R1 the second end are connected with triode VT base stage, triode VT Colelctor electrode be connected with second resistance R2 first end, second resistance R2 the second end the second end with electric capacity C, the 3rd electricity simultaneously Resistance R3 the second end connects with counter chip IC the 14th pin, counter chip IC the 15th pin and counter core Piece IC the 4th pin connection, counter chip IC second pin are connected by the control terminal of the 4th resistance R4 and controllable silicon SCR Connecing, the positive pole of controllable silicon SCR is connected with the 5th resistance R5 the second end and the second rectifier DR2 cathode output end simultaneously, the One rectifier DR1 two inputs are connected with the both ends of transformer T outlet sides, and one end of transformer T input sides is simultaneously with the One diode D1 positive pole, the second diode D2 negative pole connect with the live wire L of AC power, transformer T input sides it is another End connects with the first end of the first diode D1 negative pole, the second diode D2 positive pole and the second rectifier DR2 inputs simultaneously Connect, the second end of the second rectifier DR2 inputs is connected with loading electrical appliance FZ first end, load electrical appliance FZ the second end It is connected with the zero line N of AC power.

Operation principle of the present utility model is as follows：

The both ends of AC power and the FZ series connection of load electrical appliance are followed by 220V civil powers.Model C D4017 counter core Piece IC is connected into bistable trigger-action circuit, and for controlling switch of the controllable silicon SCR as the break-make of control load, controllable silicon SCR is led It is logical to be closed equivalent to switch, the supply of own power source when transformer T is for solving electronic switch conducting, the first diode D1 and Second diode D2 is attempted by transformer T primary, and primary voltage is limited in into 0.7V or so, can prevent that transformer T is primary Coil is burnt out, be also possible to prevent because load current is excessive and caused by output voltage it is too high.

When switching off：Counter chip IC second pin is low level, and controllable silicon ends, load power down.Now, city Electricity provides low-voltage DC by full-bridge the first rectifier DR1 rectifications and then by electron switch after the 5th resistance R5 partial pressures, The supply of standby power is ensured.

During switch conduction, counter chip IC output end second pin is high level, and controllable silicon SCR is triggered conducting, Closed equivalent to switch, load FZ obtains electric and normal work.Load FZ has electric current to flow through in loop, necessarily has electric current to flow through transformation Device T primary coil.Boosted by transformer T, then by full-bridge the second rectifier DR2 rectifications after, equally can electron switch Low-voltage DC is provided.

It can be seen that no matter electronic switch is on or off, can solve the problems, such as the power itself of electronic switching circuit. Often press remote control once, the state of electronic switch will change once, so as to realize the function of remote control switch.
