My headlight switch does not pull out to turn on the fog lights. Do I need a new switch?

What is your question?

My headlight switch has only two positions; one for "on" and one for "off". However, I have fog lights on the car which are supposed to be activated by pulling out the headlight switch. My switch does not pull out in either of the aforementioned position,s nor does it turn to any other position. Do I have to purchase a more complex headlight switch? If so, why are there fog lights if they cannot be activated with the switch already installed in the dashboard?
