This handy Remote Pressure Switch is designed for use with your flashlight mounted on your weapon. This switch fits MF Tactical models R5-350-1, R5-350-5, T6-1000-3 and Echo Series v.1 (NOT compatible with the compact R5-350-1C+ or R5-350-3C+ models, or Echo Series v.2 or v.3). To install, simply remove your light’s tail cap and screw this switch in its place. It can be used to change modes on a multi-mode light and provides for momentary activation in whatever mode the light has been set. It was 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 loop (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. The coiled cable is 12″ in its coiled state and can be extended to a full 24″.
