The SR-D-IT provides remote momentary-on activation, either separately or simultaneously, for two weapon-mounted illumination tools--a SureFire WeaponLight and an Insight ATPIAL laser illuminator/pointer. Separate plug-in cables connect each device to the switch platform, where two pressure-pad switches are integrated with a single snap-on clamp for easy attachment to your firearm's Picatinny rail forend. The 7-inch switch cable works with most rifle/carbine applications. The entire unit is weatherproof, including the O-ring-sealed plugs.
