How about those chrome buttons that come with black collars that make them sit 1/2" above the control panel surface?
It's not the chrome that bothers me, it's that people keep the black collars on them so all their buttons are atop little individual pillars.
Yeah, some folks were steered incorrectly in the past about the purpose of those rings. They are intended to go
under thin (i.e. metal) panels, as the threads on the button body don't go high enough for the nuts to tighten them down on very thin substrates. If installing onto wood panels, chuck the black plastic spacers
