Master Switches

Master switches designed to endure the demanding conditions of heavy industrial environments, such as those found in steel mills, including crane operations, coal and ore bridges, and mill auxiliary systems. These cams operated master switches are built with rugged, mill-duty construction, ensuring durability and reliability. They offer various configurations to meet different operational and mounting needs. Hubbell Industrial Controls’ master switches ensure precise cam operation and are available for both AC and DC duties, in either step type or stepless contacts, all housed within a NEMA rated enclosure for optimal safety and performance.
