Abstract
The invention discloses a direct type light-controlled and rain-controlled blend switch which is directly connected to single-phase illumination circuit without a power transformer. The switch consists of electrical apparatus, such as a bridge rectifier, a one-way controllable silicon, a light dependent resistor, a rain-controlled probe, a resistor, a capacitor, diode which are connected by circuits. A positive end and a negative end of the current run to the one-way controllable silicon through the bridge rectifier, and back to the bridge rectifier, and then return to ground leads through electric appliances. Switching of the electric appliances depends on a controllable silicon control circuit which comprises a resistor R1 for providing DC operation voltage to the controllable silicon, adiode D5, filtering capacitors C1 and C2, a light dependent resistor RG, a rain-controlled probe which switches on and switches off the controllable silicon VS upon change of resistance values at different humidity, and an LED D2 which performs voltage stabilization action and displays operation state. The direct type light-controlled and rain-controlled blend switch needs no power transformer orrelay, and has the advantages of simple structure, small volume, light weight, no faults and reliable operating performance.

Four, description of drawings:
Five, embodiment:
The rainy autocontrol switch of direct-type provided by the invention is used on desinsection at the night lamp of farmland, can cut off the desinsection lamp power supply when raining delicately automatically, thereby protect desinsection lamp electrical accessorie, makes it not damage because of rainwater.It can reduce the manpower use because of raining midnight, also can avoid some faults that may occur in the prior art, has increased dependability.This switch has a rectangle shell, and two ends are bent terminal, the cover top portion of drawing input and output respectively an aperture and a sulculus.The induction window that aperture is photo resistance, inherent two the parallel electrodes of another sulculus have been formed the circuit of the probe of rain control switch, an aluminium matter electrode, a copper electrode, the connection of shell, internal electric element as shown in Figure 1, the electric current anode of power line (1) is through bridge rectifier diode D
4Positive pole to one-way SCR VS arrives rectifier diodes D again
2, return ground wire (3) through electrical appliance (2) and form a loop.The negative half period of voltage by power line through rectifier diodes D
1Negative pole to controllable silicon VS arrives rectifier, diode D again
3Return ground wire (3) through electrical appliance (2) and form another loop.The conducting of electrical appliance (2) is by the crucial control circuit that is controllable silicon VS; Photo resistance RG with after rainy inductive probe is in parallel again with resistance R
