Thanks Sid, that is one of the first things I did.  I put a 12v mini relay in there, but the switch does pass enough current to pull the contacts.  I suppose I could go with a smaller, mini relay.  I think at this point it would be easiest to burn an input and an output on the plc to make it work.

Yeah, maybe.  It's just kind of a shame to have to go that route if you don't already have the PLC integrated.  Here is a link to a relay that has a 3V coil http://www.factorymation.com/s.nl/it.A/id.4962/.f?category=99 in case you wanna give that a go...

I agree, the PLC isn't the best.  I will look into the relay, hopefully the draw is small enough the switch will let it pull in.
