VDD2U66B-00000-000 is a V-Series Contura XII sealed rocker switch engineered for demanding applications requiring robust environmental protection. The switch features IP66/IP68 certification, UL1500 recognition, and operates reliably across an extended temperature range of -40°C to +85°C, with a roller pin mechanism that eliminates the need for lubricants. Available in 8 or 10 terminal base configurations with optional barriers, the switch provides flexible circuit options including single pole and double pole arrangements with various electrical ratings up to 10A at 250VAC. The removable interchangeable actuator design enables panel redesign without tooling changes, while multiple lens, light, and legend options provide customization for diverse industrial, marine, and automotive applications where sealing against water, dust, and debris is critical.
