exact items shown, tested from 300KHz to 3 GHz (the range of my dual port analyzer),  see traces - the two graphs on each photo show the two outputs from the relay/switch.  The photo of a unit connected with test leads identifies a particular part, the analyzer photos that follows that photo show the two states of the swtich.  These are non-latching switches, 24-30VDC actuation voltage (so these are happy with standard 28V power.  Note that the + terminal is the one closest to the side of the switch that has the text on it, if you hook it up backwards it doesn't work.  One of these has a silver glue on label instead of painted on, it has the arc suppresion diode mounted to the top, the last batch of photos feature that one, note that the scale is set for that one to 2 dB per division 

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.
