2-Section & 8-Terminal Architecture - Engineered with a 2-tier (2-section) contact block design, this switch features 8 heavy-duty screw terminals. This professional internal structure is optimized for managing dual-line circuits, ensuring complete electrical isolation for each independent pole Precise 1-0-2 (ON-OFF-ON) Control - Features a tactile 3-position rotary selector for clear manual transition between two power sources or circuit paths. The 1-0-2 logic includes a safe center "OFF" position, preventing simultaneous connections and ensuring smooth, secure switching Industrial 20A & AC-15 Performance - Rated for high-demand use with AC-15: 440V/20A, Ith: 20A, and Ui: 660V. Specifically optimized for controlling electromagnetic loads, small motors, and high-capacity AC control circuits with stable, reliable performance Standard 35mm DIN Rail Mount - Snap-on design fully compatible with standard 35mm DIN rails. This "panel-ready" open-frame component is perfect for organized installation within control cabinets, breaker boxes, or NEMA enclosures, saving space in tight setups Flame-Retardant & Safe Construction - Built with premium flame-retardant PC material and silver alloy contacts for superior arc resistance. NOTE: This is an open-type component; it must be installed within a protective housing by a qualified professional for safe operation BAOMAIN Professional 2-Pole Rotary Changeover Switch
