Description of drawings of the present utility model is as follows:

Fig. 1 is the floor map of switch.

Fig. 2 is circuit theory diagrams.

Be embodiment of the present utility model below:

Embodiment 1:

Present embodiment is organized circuit with B, load is example with the fluorescent lamp, referring to Fig. 1, shown in Figure 2, put through mains switch 4(K), power firestreak L is added to button 3(A1 through mains switch K), 2(A2), on left end contact 1(A3) and on the anode A of Q1, because A1, A2, the equal access failure of A3, circuit is not worked, as the 3(A1 that pushes button) and pin, (A1, A2, A3 are mechanical interlocked formula), power firestreak L directly is added on the load RL1 through A1, fluorescent lamp obtains high voltage (being supply voltage) and starting smoothly, and be high light shelves this moment; As the 2(A2 that pushes button), and pin, because button 3(A1), 2(A2), 1(A3) be interlocking-type, button 3(A1) reset immediately, this transfer process is finished in a flash, fluorescent lamp can not extinguish, since the connection of A2, R1 access circuit, R1 or R2, C1, R3, C2, D1 have constituted the triggering loop of bidirectional triode thyristor Q1, the control utmost point G of Q1 obtains trigger current and conducting, the size of its angle of flow is decided by the resistance of R1 or R2, therefore, selects the suitable resistance of R1 that suitable voltage that is lower than supply voltage of Q1 output is added on the load RL1, fluorescent lamp brightness descends, and be middle light shelves this moment; 1(A3 pushes button) and pin, and button 2(A2) reset immediately, at this moment R2 access circuit, simultaneously R1 withdraws from circuit, because that the resistance of R2 is provided with is bigger than R1, thereby has changed discharging and recharging the time of former triggering loop, the angle of flow of Q1 is reduced, output voltage reduces thereupon, and the brightness of fluorescent lamp reduces again, and be the low light shelves this moment; After fluorescent lamp high pressure starting, three frequency modulated lights are conversion arbitrarily just, when need quit work, and need flicking (pressing on earth) any idle button only, the button of work just can reset, and circuit quits work.

Present embodiment also is fit to the change photocontrol of incandescent lamp bulb, and it is not resembled the restriction that fluorescent lamp must high pressure starts, when starting working, three frequency modulated lights can be selected for use arbitrarily, but had better first low light, or the starting of middle light, and then conversion arbitrarily, be of great benefit to prolonging bulb life like this.

Embodiment 2:

Now with C group circuit, load is an example with the ceiling fan, referring to Fig. 1, and Fig. 2, C group circuit structure is identical with the B group.Button 6(A4), 7(A5), 8(A6) be high, medium and low shelves button, its implementation process is substantially with embodiment 1, after high pressure (electric primary voltage) starting, any as required again conversion rate, present embodiment also has characteristics, it do not resembled the fluorescent lamp must the high pressure starting restriction, in, low grade also can start smoothly.According in, the requirement of low speed selects R5, the suitable resistance of R6, the third speed control that can realize ideal to ceiling fan.

R4 in Fig. 2 .B group, C3, the R8 in the C group, C6 is Q1, the over-voltage protection element of Q2.

Advantage of the present utility model is as follows:

1, the utility model is double loop three driving switch, can control two loads, when the control illumination, can realize a lamp three usefulness (i.e. variable three kinds of light of bulb), it is especially convenient to use up, and can replace the big inductance speed regulator of traditional power consumption when being used for ceiling fan speed regulation, and volume is little, in light weight, cost is low.

2, according to different instructions for uses, can be assembled into single loop, double loop or multiloop also can be assembled into two gears, and the switch of three gears or many gears satisfies various instructions for use.

3, because overall dimensions are the same with common concealed installation switch, so project installation is supporting easily, and it is also convenient especially to change old switch; Join different bases and close, but concealed installation also can brightly be adorned.

4, no matter load characteristic how, so long as be in high tap position, all be that supply voltage directly is added in the load, ghyristor circuit only starts to control making usefulness in middle-grade and low grade, has avoided the influence of big electric current (impulse current was very big when particularly fluorescent lamp started) to electronic component.Thereby improved the reliability of circuit.

5, applied range not only is fit to enterprises and institutions and uses, and be particularly suitable for family and use, stable performance, easy to use, have tangible power savings, can also improve power factor (as ceiling fan), through use more than a year, working stability is reliable.
