1996 GMC Jimmy Hazard Light Button

I turned on my hazard lights the other day and the red button that controls them snapped off. Now the hazard lights stay on alll the time unless the fuse is removed in which case my brake lights and turn signals are out. Where do I go to get this part? Is it easy to replace on my own? The GMC dealer said to visit a junk yard - but how do I remove it from the other vehicle? Is there a way to bypass the hazard light altogether?
