[quote=mkenney;567440]Still working on it. When off the output pin is at .535Volts and when on it is at .022Volts. Any chance you could tell me what yours are showing. Starting to pull my hair out on this one:-)

With reference to ground or +VCC? I will bench test it today. OK, I just tested it. With an input voltage of 5.27V, between the output pin and ground I get .512V with no magent and .008V with the magnet. This switch is a current switch not like a regular mechanical switch. The voltage does not mean much. When the switch closes, it allows current to flow, so the reading of .022 looks correct for you. Think of it as reading across a mechanical switch, when it is closed you will not see any voltage. I still don't fully understand these solid state switches, but as long as they work, I don't try to. The change in voltage you are seeing tells me your switch is working.
Depending on the break out board you use and how their logic is wired, it could take from no resistor across the output to +VCC to 10K and just about anything in between. The resistor is to provide a voltage drop across it when the switch allows current to flow so the BOB can see a voltage at the pin.
