Hi guys,
Please help in this
I want to make circuit in which i don't want to interfere with switch. In this circuit when I turn on the switch... One function is on and other is off and if again switch off and on, the other function start working.

Ex:
In circuit there are
supply, switch ( on off), led 1, led 2

When,
Switch off, led 1 off and led2 off
Switch on, led 1 on and led 2 off
Switch off, led 1 off and led 2 off
Switch on led 1 off and led 2 on
This pattern repeat
Please help me out
If there other option you can give me

 

not sure what u want to achieve by doing that, it's impossible to my knowledge now without the help of some sort of MCU.
However, you may try some simple SP3T switches like these >> http://my.element14.com/c-k-components/pcm13smtr/switch-sp3t-0-3a-6vdc-r-a/dp/2320077
