I am still working out the details of my control panel layout, but I know that I am going to use these – genuine Atari ‘volcano’ start buttons. I ordered them from RAM Controls. The switch is NOS (“New Old Stock” – 25 years old but never used) and the cones are high-quality reproductions. I think these will complement the stainless token top spinner knob very nicely.
I got a kick out of the old hand-typed label too.
