Inland RV has them as well as Ace Fogdall RV in Iowa. I contacted Florence at Fogdall at 1-(800)747-0747 on the advice of one of the forum members and bought 2 of the round knobs for that switch. They had switches at that time 3/13/02 and the forum member had one he had ordered from them that what not what he wanted but was the part I needed (thanks
thenewkid64). Yes, I have heard that they are available at Home Depot but were not available at the Lowe's near me.
