There should be .020 space all the way around the key, if there is an overlay that goes on the top of the bezel then overlay can come in another .005 to cover up the key whole opening. If there will be no overlay we can have .015 space around the keys. Bezel should never sit on the web area. Web area is approximately .040 high and .040 spread. Best tactile feel comes when there is about .047 to .050 travel for the key. Web area is designed by the tool maker to give the required force by the customer.
