Hi, I have no real experience with creating electronic circuits but I am familiar with the fundamentals.
I need a very simple circuit to create a loopback on a switchport, so there is no "load". The loopback just needs to connect pin 1-2 and 3-6 of the 8pin connector and it probably needs to be low resistance (I'm actually not sure how low but I'm guessing < 5 ohms). So far I've only been able to achieve about 80 ohms with a transitor. I've tried adjusting resistors but can't get it lower. I'm guessing this has something to do with saturation but since most transitor circuits deal with amplifying, I'm not finding relevant info for my case.
Can this be accomplished with a transitor circuit or do I need to use a relay. If relay, can anyone recommend a part number for something readily available. It needs to be as small as possible.
Thanks
Ron
