    Help with a circuit.

    First question - the Rotary switch. Yes, the same way as I and you have described. Second item - the Extractor fan. I have a small 5V PC style Fan which I will mount in a box with a Carbon filter and then route it out back into a pipe. For now, the 5V will do. Third question- what goes here...

    Thanks very much, old chap, I shall now explain why I have so many switches. The circuit with the RED LED is what I am building now. Basically, the Red LED is a pilot light to show whether the voltage is on or not at the switch. You may have noticed a larger switch next to it. This larger switch...

    You might have noticed in the photos, the Green LED is on when having the rotary switch in the top position. Move it to the right one spot allows me to turn on the Red LED. However, when I do this the Green LED does not stay on and only comes on when I flick the toggle switch by the LED. I want...

    Help with a circuit.

    Right so, my problem is that switch the Rotary to No2 connection both lights turn off. I want the Green LED to be on all the time no matter what switch I open or close. I will have a picture of the circuit later.

    Help with a circuit.

    Hi I recently made a circuit, ran into a problem. It's not huge, the circuit still runs well but I would prefer to iron it out. Basically, I have a key switch, + voltage goes to a panel mount Voltmeter and the - from the voltmeter goes to a Green LED. The - connection of the Green LED goes to...
