The RSW2 Remote Pressure Switch from Nitecore replaces the stock tailcap on compatible flashlights for safe use with weapon-mounted lights. Its coiled cable extends to 15", allowing you to precisely place it according to your personal preference. The pressure pad attaches whereever your stabilizing hand goes, providing momentary-activation for the light while keeping both hands on your weapon. A pushbutton switch on the side of the tailcap gives you constant-on for prolonged use.
