For me the wheel works fine but the push to select or change a setting is the fiddly part. If it's simply a momentary contact closure that's needed, couldn't we just add a separate button? Has anyone disassembled the switch enough to determine if there's a way to solder in an external momentary switch in place of the wheel press? i.e. leaving the roller part of the switch functional but adding a momentary button that is guaranteed to work as needed?
