Extron SW VGA 系列为使用15 针HD 连接器的有源切换器。系列中共有6 种切换器。SW2 VGAr、SW4 VGAr 和W6 VGAr 分别为2 路、4 路和6 路输入、 1 路输出切换器，允许将多个 VGA-QXGA 计算机输入切换到一个兼容显示设备上。
SW VGA Ars 系列是具有 8 路和 12 路输入的 VGA 和立体声音频切换器。它们设计用于需要将多个高分辨率计算机视频和 HDTV 分量视频信号切换到最多两台显示设备的应用环境。SW8 VGA Ars 和 SW12 VGA Ars 可兼容高达 QXGA 的计算机视频分辨率，并且具有双路缓冲输出、输入信号感应、自动输入切换和多种控制模式等特性。两种切换器都与高分辨率 RGBHV 计算机视频信号以及带三电平同步的 HDTV 分量模拟信号兼容，因此特别适用于需要高分辨率切换的中、小规模的应用环境。
