Arrow Hart 27900 Selector Switch 2-Position 600V AC

Arrow Hart AH27900 B-5-A selector switch, a two-position device rated for up to 600V AC, is designed to provide a simple, reliable method to select between two electrical circuits or control paths in industrial equipment. In practice, this type of switch is used wherever a binary choice must be made within a control system, such as routing power or signals in manufacturing lines or processing equipment that operate on high‑voltage AC. The AH27900 family is cataloged by Arrow Hart as part of its industrial switch lineup, with three-position variants listed for more complex, two‑circuit applications, though the configuration described by the product title here is specifically the 2‑position, 600V AC, B‑5‑A variant. This model emphasizes straightforward manual operation and compatibility with standard wiring practices for 600V-class circuits, making it suitable for upgrades or replacements in legacy control panels that previously used a B‑5‑A selector switch. When selecting a replacement, verify the exact B‑5‑A contact arrangement and the 600V AC rating to ensure proper fit, electrical compatibility, and safe operation in your equipment.
