LAY5-BD21 22mm Metal Selector Switch – 2-Position Stay Put
The LAY5-BD21 Selector Switch is an industrial-grade, heavy-duty control solution engineered for reliable, manual two-position circuit selection. Built with a rugged chromium-plated zinc-alloy bezel and a high-performance, flame-retardant contact block housing, this switch is designed to withstand harsh industrial environments. It features a sleek, black short handle with a 2-position "stay put" (maintained) mechanism that locks firmly into position at 90-degree intervals. Equipped with a high-capacity, self-cleaning normally open (1NO) contact block, it ensures excellent electrical conductivity and highly responsive operations in motor control circuits, automation panels, machinery overrides, and power distribution setups.
