Materials: Copper, Bakelite
The pushbutton is a new, old stock 30mm oversized obsidian bakelite and chrome industrial Weiser brand momentary switch that can activate any standard 2 or 4 wired bell service. Screws of pure copper make for an excellent addition but can be substituted with black or brass of your choice.
The pushbutton can also be a standard 16mm mother of pearl and chrome if requested instead, please see last photo.
