i am using a axial fan of 12v
2 led(green and red)20Ma and 5mm
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 u also c if the values of the resistors are fine

Yep the resistors are ok,but u should put a freewheel diode in parallel with the motor cause as you turn it off large voltages will appear across its terminals and this may damage your led with time.
What's the point on switching to the off position just lighting the RED LED?
Why not have only ON & OFF? ON = GREEN, OFF = RED. IF you do not want to drain the battery while in off position, just forget the RED lED altogether. ON=GREEN, OFF=NOTHING. 3 switch positions seems silly.
I agree, it's wrong and looks plain silly when people say things like MA when they mean mA and mHz when they mean MHz but I gave up moaing about it awhile ago.
