The 7" cable Rail Grabber Pressure Switch from SureFire is a remote pressure pad activation switch for the M720V weaponlight. The 7" cable is a replacement for the switch that comes with the light. A dovetail mount allows the switch to slide onto a Picatinny/Weaver rail, for solid installation. Installing the switch directly to the rail eliminates the need for tape, which can fail over time or in extreme conditions. The switch provides momentary and constant-on activation options for the light.
