For the majority, the need for a constant-on function is essential, and for others, the requirement for a momentary-only option is equally as important. Our latest Dual-Button REIN remote switch provides both features while being even better than ever. The Dual-Button enables users to activate their REIN weapon light in either constant-on (X) or momentary-only modes using a single switch. Each button functions identical to their respective single-button counterparts mentioned above.
