If that is the same switch Powertec 71054 I looked at on Amazon,it is a magnetic switch and the coil for the holding relay is across 14 and 24 so the dc resistance should be very low ,basically measuring the resistance of the wire.Most continuity detectors will show this as a short.If you are ok with electricity,You can test it with power connected to the input from a power strip and nothing connected to the output just to see if it trips the breaker on the power strip and has voltage at the output terminals
