This handy Remote Pressure Switch is designed to be used when your flashlight is mounted on a weapon. The Olight Remote Pressure Switch fits the M31, M3X, M21, M20, M20S-X and M20 Crimson LED Flashlights. It momentarily activates whatever mode the light has been set to and is made to be used with any long gun- rifle or shotgun (not for pump action weapons). It fits into the integrated pressure switch pocket of a fore grip, and the pressure switch can also be attached with hook and look (not supplied) to any weapon that does not have an integrated pressure switch pocket. It has no "click" sound and can be easily used when wearing gloves.
