Wiper switch knob

Hey guys, I'm in need of experience, I'm in process of pulling my dashboard and I have everything down except for this darn wiper switch knob is giving me pain..does it pull off cause I pulled on it with some pressure and it doesn't want to give I'm afraid to break it or switch itself..wife had friends over today so I've been able to stay in garage abandoned from house..got a whole lot done too..any help would be appreciated..I tried a search couldn't find anything..
Thanks
