Have a look at the PDF file that can be downloaded from my web site for wiring diagrams of two different types of CDU.
The CDU I designed that uses normal switches and NOT passing contact type may be of interest to you.
This circuit uses transistors instead of relay contacts so the switching would be more reliable.
The design was inspired by the "Masterswitch" unit sold by Bromsgrove models and can easilly be addapted for use on DCC systems.

Here is the link to the page on my website.

Click on to "normal switch type CDU to open or save the Acrobat file.

Hope this helps
Kind regards
