Abstract
A mechanism for bypass isolation switches of the type comprised of at least three circuit interruption devices each having a handle has at least three switch gears, one positioned over each circuit interruption device and having either a drive gear or a spacer gear therebetween. A cam having a mouth which engages the handle of the circuit interruption device is eccentrically mounted on each switch gear. A stop is provided on at least one gear to permit the gears to rotate only 180.degree.. Since the drive, spacer and switch gears are interconnected, the cams must move or not move simultaneously. As a result, the at least three circuit interruption devices are operated simultaneously.
