The Snap-Lug power connectors are used in military ground vehicles, commercial aviation and industrial commercial vehicles. These connectors are color coded and keyed for polarity to help prevent damage from accidental polarity reversal. The design saves time through a snap-on/push-to-release installation feature. The self-locking connector can also withstand high vibrations and extreme temperatures to enable continuous power in harsh environments. The shrouded, isolative design has no exposed metal, enabling a safe connection of power.
