AC and DC

[dumpy]

Thanks for that idea which is an alternative I hadn't thought of, though I did consider using the uncontrolled DC output of another controller. However I have limited space in 'My Command Module' so am trying to restrict myself to the one LGB transformer. Thus I think it will be the diode route since I have plenty of these.

You learn something every day. After agonising over AC and DC, diodes and rectifiers, when I came to look, the LGB momentary switch boxes already have diodes in them. No problem, connected 4 switches today and hey presto.
