VJD2U66B-00000-000 is a V-Series Contura XII sealed rocker switch designed for demanding applications requiring robust environmental protection and reliable switching performance. The switch features IP66/IP68 certification and UL1500 recognition, with a roller pin mechanism that eliminates the need for lubricants and enables operation across an extreme temperature range of -40°C to +85°C. It is available in multiple terminal configurations (8 or 10 terminal bases with or without barriers) and supports various circuit ratings and illumination options with interchangeable actuators for flexible panel redesign without tooling changes. The switch effectively seals out water, dust, and debris, making it ideal for marine, industrial, and automotive applications where environmental sealing and temperature extremes are critical requirements.
