Programming Track Switch Automatic by NCE Auto-SW – #524-AutoSW

Connect the output of your PowerCab to the AutoSW and connect the layout to one set of terminals and the programming track to the other. When you go into the programming mode, the AutoSW disconnects the layout and connects the PowerCab to your programming tracks!

ATTENTION, DIGITRAX USERS: the AutoSW works on DB150 powered Digitrax layouts, too, like the Super Empire Builder!
