Gen 4 Switches

Does anybody know where I can get a light switch to go in the spare spaces on the right hand lower of the dashboard, and how does the cover for the switches come off. I have looked at the Swift switches and the Toyota one as well as I was told these fit but they are too big. I want to install a light bar I have all the wiring and the light is ready for mounting, but would like a proper fitting switch that is keeping with the rest of them.
