The Z61 switch gives you both momentary or constant-on flashlight activation without having to rotate the tailcap, as is the case with our classic tactical switch. Push lightly on the tailcap for momentary activation, push harder to "click" the light into constant-on mode, click again for off. Precision machined aerospace-grade aluminum construction, hard anodized in Black. Lock-out feature prevents accidental activation of light during tactical operations, transportation, or storage. Also available in Olive Drab as the Z57.
