Daylight Switch Circuit Diagram. The entire circuit of this 12 volt day night switch can be built over a small piece of general pcb and the whole assembly along with the transformer may be housed inside a good. The black wire power in source attaches to one of the switch screw terminals.
Then we apply the above circuit to make the automatic air pump. We should make a 9 volts dc power supply and connects them together as figure 2. The source is at sw1 and 2 wire cable runs from there to the fixtures.
Circuit electrical wiring enters the switch box.
The entire circuit of this 12 volt day night switch can be built over a small piece of general pcb and the whole assembly along with the transformer may be housed inside a good. This diagram illustrates wiring for one switch to control 2 or more lights. Since we have 12v ct 12v or 24vct transformer so set this circuit form. The black wire power in source attaches to one of the switch screw terminals.
