Switch Tactics. The DS-SR07 is a waterproof switch assembly for most SureFire's Scout Light® WeaponLights (excludes Micro Scout Light Pro). It includes a system disable feature, click-on/off pushbutton switch, and a plug-in SR07 switch assembly with a 7-inch momentary-on and click-on/off remote tape switch. The integrated pushbutton and remote switch assemblies operate independently, providing switch redundancy.
