The Teletypewriter Selector Bar is a component of Teletype and Facsimile Equipment, which falls under the supply class of Communication, Detection, and Coherent Radiation Equipment. The selector bar is a mechanical device used in teletypewriters to select and position characters for printing. It consists of a row of keys or buttons, each representing a specific character or function.
