i am national diploma student . i would like to ask if anyone can do a circuit diagram for me.
i am using a axial fan of 12v
2 led(green and red)
battery 12v
switch
what the circuit should do when the switch is on the green led should turn on also the fan and when the switch is turn off the red led should turn on and fan should be off.
can you also include resistors and anyother other things
We will not do your work for you, please check the rules! "Please do not ask for complete circuit diagrams!" As far as i know, thi can be done with a switch and some resistors.

You should be able to figure this out. The switch will have to be a SPDT (3 terminals) with +12 going to the center pin, and that is all the hint you will get from me
first of all u don't exactly need circuit diagram.you don't know how to connect all these thats why you asked circuit diagram.
and the problem with ...ian ppl is the way the ask the help is really bad.they just don't request.but they demand it.this is what most ppl don't like.so be careful from next time.
above methods are good and cheap.
but i used a NO/NC 12v relay for this purpose.
**broken link removed**
use v=ir formula to calculate the resistor value.

right side 2 pins are coil,and left side 3 pins are common,NO,NC

Let me add something to increase his confusion. You can also use the SPDT with the center pin going to the motor, and the outer pins to +12 and GND. There are lots of ways to connect a simple switch. There is only one wrong solution - shorting +12V to GND. One more hint: Take your destop lamp apart and look how the switch is wired.

it's a pleasure for me to post an appropriate circuit here. I must admit using an SPDT does not offer that many switching combinations as they can be performed by two SPSTs.
Note: I just explained three different switch positions. Especially the last mentioned combination will cause some special effects.
Hans (I thought your name was Herman), I was confused by the above quote. To me, that meant you were going to connect the switch pole to the motor, one end of the battery to one of the switch throws, and the other end of the battery to the other throw, and the other motor terminal somewhere. Somehow, I figured you were going to take this scheme, add some resistors and LEDs, and come up with the function that the OP wanted. I guess I misunderstood you.

Yes, I go along with that. However my intention was to make him think of his own a bit. The third position as posted is the so called power saving mode. (Everything off, perhaps some smoke )
BTW, my full first name is Hans-Juergen. Most foreigners tend to break their tongues trying to pronounce that correctly. Therefore I skipped the Juergen.
Herman (the Cherusker) was the most famous German of all. He kicked the Romans out of Germany. (some time ago) I kicked russian mine sweepers to the bottom of the Baltic sea.
