The V6D1K66B-00000-000 is a Contura IP66/68 sealed rocker switch manufactured by Carling Technologies, a Littelfuse brand, designed for snap-in mounting in demanding environments. This switch features single-pole or double-pole circuit configurations with 8 or 10 terminal bases, offering flexible terminal arrangements with or without barriers to accommodate various electrical requirements. The switch is rated for 0.4VA at 28VDC resistive, 15A at 24VDC, or 20A at 12-18VDC depending on circuit selection, and operates reliably across a wide temperature range. It has passed rigorous environmental, corrosion, vibration, and shock testing standards including MIL Std 202F, MIL Std 510.1, UL 1500, ISO 8846, IEC 60529, and BS 5490, making it one of the most rugged and reliable switches available. The switch is ideal for on/off-highway vehicles, marine vessels, armored vehicles, mining machinery, and any application requiring robust sealing protection and environmental resistance.
