From increased tactile response to a larger switch surface, a lower height profile, and improved cable management, these design improvements on the new Cloud Defensive Single Constant Weapon Light Switch represent a natural evolution shaped by user feedback and real-world data. Every switch remains cross-compatible with all REIN weapon light platforms. Whether you have an original REIN 1.0 or the current generation, every REIN user can benefit from these 3rd generation enhancements. And as before, these remote switches are designed with built-in operational redundancy. This means if your remote switch ever fails, your REIN can still be operated using the tailcap push-button, as they operate electrically independent from one another.FeaturesSingle push of the button - Activates the light in a constant-on mannerSlight press of the button - Deactivates the light for momentary-off applicationsFull push of the button - Turns the light back off
