Abstract
A center-pivoted, conductive vane equipped with contact-enhancing finger stock on the wiping edges rests during normal operation of a modified waveguide section parallel to and equidistant between the broad faces of the waveguide, where it interacts minimally with RF propagating through the waveguide. When it is desired to provide a short circuit to the waveguide, for a safety lockout or other uses, the vane can be rotated into a position to provide a substantial barrier to RF propagation. Rotating the pivot shaft, to which the vane is rigidly attached, performs rotation of the vane. The shaft is equipped with lockable stops for the open and shorted positions. Multiple center-pivoted vanes in a multiple-branch waveguide can form a switch.
