Fuzz button

• abstract: A Fuzz Button is a high performance 'signal contact' typically fashioned from a single strand of gold-plated beryllium-copper wire formed into a specific diameter of dense cylindrical material, ranging from a few tenths of a millimetre to a millimetre. They are often used in semiconductor test sockets and PCB (board-to-board) interconnects where low-distortion transmission lines are a necessity.
