Switches with adjustment dials are not a specific brand but a category of industrial components used for precise control in various applications. These switches are typically offered by multiple manufacturers, such as Honeywell (USA), Omron (Japan), and Schneider Electric (France), which produce them for industries like automation, HVAC, and machinery. Key products include rotary switches, potentiometers, and encoder dials, enabling adjustable settings for voltage, current, or operational parameters. Companies like Radwell and Grainger distribute these components, sourcing from global suppliers to serve maintenance, repair, and operations (MRO) needs.
