SureFire DSE Dual Fuel Switch Tailcap Assembly - M600/M640 Dual Fuel Scout Weapon Lights & BSL-A Switch

SureFire DSE Dual Fuel Switch Tailcap Assembly
Compatible with M600/M640 Dual Fuel Scout Weapon Lights & BSL-A Switch

Ensure fail-safe activation and maximum switching performance for your tactical lighting setup with the SureFire DSE Scout Light Switch. Engineered as the genuine OEM replacement dual-switch assembly for SureFire M600DF, M640DF Dual Fuel Scout Lights, and the BSL-A Ballistic Shield Light, the DSE is built to maximize current delivery for high-output 6-volt weaponlights. Featuring an integrated pushbutton alongside a remote cable switch receptacle, it operates each method independently—providing mission-critical switch redundancy so you never lose light when navigating low-light engagements.

Constructed from Mil-Spec Type III hard-anodized aerospace aluminum and fiber-reinforced polymer, the DSE is O-ring gasket-sealed to repel moisture, grit, and harsh environmental elements. Its innovative two-piece housing swivels to allow precise, custom positioning of the click-on/off pushbutton to match your grip and rail setup. Equipped with a positive tailcap lock-out feature to prevent accidental battery drain during storage or covert tactical operations, the DSE offers elite reliability and seamless compatibility with SureFire ST07, SR07, and SR07-D-IT remote tape switches.
