Fog Lights won't turn off

My fog light switch is on the directional signal stalk. As of yesterday it won't turn off. If I push in on the stalk the lights go out, as soon as I release the pressure they come back on. I've read somewhere that the factory fog switchs suck and are prone to break.
I'm thinking of bypassing the switch and putting in a toggle switch. Any suggestions?

You could take the switch apart and repair it, another member did a nice write up with pics to show how Write up to repair multifunction switch

Or if you look around there are a few write ups on bypassing with a toggle, and one I did to show how to replace the whole switch itself

Replacing the switch is easy enough, if you want to go that route.
In the meantime, put your left signal light on when you park, worked for me to keep the fog lights from coming on.
See this Thread for replacement:

I replaced 20 pin connector as well as MFS Switch today and lights finally turned off but would come on when bumped or turning right. I decided instead of risking melting another $60 connector I would use a toggle switch for the fogs. Cut the large White wire with orange tracer and put power and ground to it. Now a little less current going through the MFS switch and fog lights that are on when I want them on.
