All components and parts are contained on the wiring board, and wiring board is fixed on shell B by two screws and goes up integral body of formation.

Description of drawings:

Fig. 1 is a schematic appearance of the present utility model

Fig. 2 is an electric functional-block diagram of the present utility model

Fig. 3 is circuit theory diagrams of the present utility model

Among the figure: the 1st, light-operated hole, the 2nd, touch point A, the 3rd, night indicator light L ₁, the 45th, fixing hole, the 6th, the output control line hole, the 7th, power input hole,

Below in conjunction with drawings and Examples the utility model is done further and carefully to be stated: as shown in Figure 3, after connecting alternating current 220V 50Hz power supply, night indicator light L ₁Pass through resistance R ₁Light after the step-down, voltage passes through capacitor C ₁After the step-down, through rectifier bridge B ₁Rectification, the pressure stabilization function of voltage-stabiliser tube DW and filter capacitor C ₂Filtering, obtain direct-current working volts that adapt to the change in voltage broad, make this switch in running order.

When the staff touch, during the A of touch point, its induced signal passes through N ₁Amplify, pass through diode D again ₁Detection, become the signal of comparison rule, this signal is through delay circuit, in capacitor C ₃And resistance R ₃Control under obtain needed time-delay, and then by N ₂N ₃Carry out secondary and amplify, so just obtained stronger signal voltage, but because the load capacity deficiency must be passed through function control device again by UT ₁UT ₂The multiple tube of forming amplifies, and signal voltage is strengthened load capacity greatly like this, makes relay J L adhesive.Contact J1-1 connects, because the conducting of J1-1, controllable silicon is by the bidirectional trigger diode conducting that is triggered.So just utilize the silicon controlled break-make to control the switch of electric lighting.

Because this circuit also has light control functionality, in relay contact J1-1 control silicon controlled circuit, added light control system, when the same day, the black light line was not enough, photodiode DW made circuit turn-on, when the same day, bright light rays was sufficient, photodiode DW, circuit is closed, thereby realized electric equipment, touch the light-operated function of time-delay.

N ₁-N ₃Be general NAND gate circuit.
