ONE good switch (picts are samples of available at time of listing, if it matters which ASK first) Each one was tested for: Continuity on each of the 5 ports Continuity on grounds Visual internal inspection of the switch contacts and wiring, and we verified free of any cracks or thermal stress. Visual inspection of threads (these do not look worn, were probably set up and left in place during prior use) Has the older silver plated Amphenol PL259 type connectors that as you may know, are far better then newer nickel ones. No knob is included but if you need one ask maybe we can find an extra. Fits standard type.
