This little module is the means for my staging table to get its DCC power. Since I am not doing any switches on this module, I will only need "+" and "-" , hence the two connections.
These little hidden switches were recommended to me by a friend's father-in-law who rebuilds HotRods. He said that the car guys use these for door switches, to keep thing nice and clean on their builds. Looks like a great piece to use.
If you are interested in these parts you can find them at http://www.streetrodhq.com. Search for SDXB and SDXT (these are in 'pairs' - male and female sides - but I needed two connectors. A top and bottom. If you need more connectors you can buy inner pieces).
