Re: Rotary switch
To see how to do it go to www.wiringfordcc.com and look in the index for and/or scroll down to section "f" of the advanced Slo-motion switch motor control.
Sorry... I lost my list of easy links to various subjects.
Another method is to use the Team Digital SRC16 and use a single push button to select and enable a particular yard track with internal programming set up to correctly adjust up to 8 turnouts for that track path.
