Background technology

Fig. 1 is the electrical schematic diagram of civil power lighting lamp switch, the wire illuminating lamp (2) of having connected wherein when AC220V two wires are drawn out to the switch (1) of wall (3), like this as long as switch (1) closure, the illuminating lamp of being controlled (2) is just bright, this is the operation principle of regular tap, if but the two-wire system supply power mode that this power supply of light switch is connected with load is controlled with electronic switch, just very difficult, because the semiconductor device that electronic switch is used, such as: integrated circuit, transistors etc. all are active devices, must supply with their necessary operating voltages and operating current ability operate as normal all the time, and all these required electric currents of electronic switch all can flow through the filament of illuminating lamp (2), if it is big to supply with the operating current of electronic switch, incandescent lamp shadow is rung little, but then can make it not stop to glimmer and can't normally use when being used to control electronic energy-saving lamp and fluorescent lamp, and the electric current of supplying with electronic switch little with the executive component controllable silicon or the actuating of relay of motionless electronic switch, realize the due function of its switch, this type of product still belongs to blank on market at present.

The utility model content

For addressing the above problem, the utility model has designed the executive component as electronic switch cleverly---the tie point of bidirectional triode thyristor SCR in circuit.No matter bidirectional triode thyristor SCR conducting or turn-off, all can guarantee the operate as normal of control circuit, and when bidirectional triode thyristor SCR turn-offs (electric light does not work), the consumable electrode of electronic switch itself is little, and the problem that makes fluorescent lamp, electricity-saving lamp produce flicker when using electronic switch is well solved.

The purpose of this utility model be to provide a kind of can be on wall or the telecontrol electronic switch of installing in other box body.

The purpose of this utility model is to realize like this, see Fig. 2, it is made up of step-down current-limiting circuit (1), rectification filtering voltage stabilizing circuit (2), signal decoding circuit (3), remote signal receiving circuit (4), electronic switch circuit such as (5), and this circuit can be contained in the box body of any material and shape.Be applied in the two-wire system supply power mode that the alternating current 220V civil power connects with load, its advantage is: 1, may command fluorescent lamp, electricity-saving lamp, 2, itself very little from power consumption, 3, remote-controlled.
