It's easy enough to just undo the two strap screws, pop the two tabs off of each side, & pull the panel off. Then you can pop the switch out & replace. This way makes it easier to remove the switch if it still has the support frame on it.
For what it's worth, less than $30 I would replace the two strap screws with threadserts. Can get the tool at Harbor Freight. This way you can actually pull on the straps & no longer have to worry about just sheet metal screws holding it. When I did mine, I threadserted the strap holes and the holes for the armrest. Great piece of mind for me since I had the panels off anyway.
