exact item shown, NARDA 4PST switch, 28VDC SEM143 line, I tested the switch with an ohmmeter to be sure the poles are all good, I didn't see much value of testing with an analyzer.  I verified 50 ohm termination on each of the 4 poles and that latching works properly

Note to me: computer hutch, left side

I normally ship within 24 hours of your order, but the post office does not always initiate tracking when I put the packages in the drop off box.
