Product Info for Unity Tactical Modbutton Lite Single Lead Surefire 4.5in Switch

ModButton Lite is a smaller, lighter cousin to the original ModButton. The switch features the same momentary only activation as the original ModButton. It also features the same high-power cable and switch from ModButton, but in a slightly smaller package without the integrated mount. The switch is made from injection molded plastic, providing an extra degree of protection in harsh environments and ensures a durable long-lasting switch.ModButton Lite is designed and patented by UNITY Tactical. It is produced exclusively for the Modlite brand and supports power delivery needed by the next generation of high-output weapon lights. It is compatible with UNITYs LINK System and GASCAP USB-C Tailcap. A UNITY-built SureFire-compatible 4.5" cable lead allows ModButton Lite to be backwardly compatible with all SureFire, Arisaka and Modlite Scout bodies, as well as SureFire UE and DS00 tail caps.image
