For shooters who prefer momentary-on white light applications, this low-profile remote switch offers optimized space and ergonomics without compromising functionality. A single press activates your REIN weapon light in momentary-only mode, keeping the light on only while the button is pressed and immediately turning off when pressure is released. The latest generation of REIN remote switches includes enhancements like increased tactile response, a larger switch surface, a lower-height profile and improved cable management, all shaped by user feedback and real-world data. These 3rd generation switches are cross-compatible with all REIN weapon light platforms, from the original REIN 1.0 to the newest models, ensuring all users can benefit from the upgrades. Built-in operational redundancy means the tailcap push-button remains functional even if the remote switch fails, providing reliable performance in critical moments. Made in the USA from impact-resistant polymer and IPX-8 waterproof rated to 100 feet for 24 hr, this switch is designed to withstand tough conditions while delivering precision control.
