The Remote Pressure Switch is designed to work with all of the TAC-300 & TAC-400 Series LED flashlights. It replaces the tail switch and permits remote operations of the flashlight in momentary mode. The side switch button allows the light to be used in either momentary or constant-on mode. With the addition of any 1 inch scope or flashlight mount, the Remote Pressure Switch turns the TAC-300/350/400/450s into one of the best long-gun lights on the market. Includes the Velcro and pressure sensitive adhesive strips for mounting the pressure switch anywhere the user would like.
